Coles Credit Cards

and make sure they reply?

The fastest route to Coles Credit Cards customer service in Australia is 1300 306 397 — and the team that answers works for National Australia Bank, not Coles supermarkets. NAB (ABN 12 004 044 937, AFSL and Australian Credit Licence 230686) has been the credit provider behind every Coles-branded Mastercard since 1 June 2022. Coles Supermarkets distributes the cards; NAB services them.

This page covers the Coles Rewards, No Annual Fee, Low Rate and legacy Coles Group Source Mastercards. For groceries, Coles Online orders or a Coles Gift Mastercard, start at the Coles Group contact page — completely different teams.

Support channels for cardholders:

• Phone (Australia): The main Coles Credit Cards contact number is 1300 306 397, available around the clock for lost, stolen or suspected fraudulent cards.
• Phone (overseas): +61 2 8288 2890.
• Live chat: Inside the app or Online Service Centre, 8am–10pm AEST/AEDT, seven days.
• Online Service Centre: Secure login at secure.coles.com.au for statements, payments and card controls.
• Mobile app: Coles Credit Cards on Google Play and the Apple App Store — published by NAB.
• Payment difficulty: 1300 194 546 (Mon–Fri 8am–8pm, Sat 9am–1pm).
• Financial hardship: 1800 931 356 (same hours) or hardship@secure.coles.com.au.
• Written enquiries: The Coles Credit Cards contact form for anything that isn't time-critical.

What to expect before you make contact:

• Accounts moved off Citi's legacy systems onto NAB's on 8 September 2025. Account numbers changed and the old app was retired — see the Coles Mastercard transition page.
• Public sentiment is poor, and it lands on servicing rather than the products. The Coles Rewards Mastercard sits near 1.6 out of 5 from 343 reviews, the Coles No Annual Fee Mastercard near 2.3 from 216, and the replacement app around 1.2 from roughly 693 ratings.
• The upside is real: because NAB holds the credit licence, you get regulated internal dispute resolution timeframes and free access to the Australian Financial Complaints Authority. Reviewers rate the fraud and disputes teams well above the general contact centre.

Coles Credit Cards login problems after the NAB migration

• The single most reported issue since September 2025: lock-outs from the app and Online Service Centre, and registrations that won't complete.
• Customers describe being unable to update an email address or mobile number, or to view balances and transactions for weeks.
• Some report server-side errors thrown by NAB's identity service at the login step.

Who issues Coles Credit Cards NAB or Coles Supermarkets?

• The card is Coles-branded but NAB-issued, so customers routinely dial Coles supermarket care or NAB's main retail banking line and get bounced between them.
• The only correct line for card servicing is 1300 306 397. Lead with "Coles Credit Cards" when the call connects.

Coles Credit Cards app not working

• Crashes, freezes, load timeouts and an app that won't open at all dominate recent store reviews.
• Lost feature parity is the other recurring theme — the running "balance required by due date" figure and an at-a-glance Flybuys points balance are both missed from the Citi-era app.

Long waits and repeat transfers

• Holds of 40 minutes to over an hour are commonly reported, sometimes across several calls without a resolution.
• Several reviewers flag offshore handling and being passed between teams with nobody owning the case.

Statement and transaction visibility

• Statements have been difficult to retrieve since the platform change.
• Duplicate entries appear — PayPal debits showing as both pending and settled — alongside delays in transactions posting.

Disputed transactions and fraud chargebacks

• A genuinely mixed picture: proactive fraud detection draws praise, drawn-out disputes draw criticism.
• Some customers had a temporary credit reversed when a dispute failed, then were charged interest on the reinstated amount.

Changes that reduce card value

• Reviewers report cuts to interest-free days and rewards earn rates plus new international transaction fees. Coles publishes these formally as variation notices.
• From 1 October 2026, the documented Flybuys earn is 2 points per $1 at Coles Supermarkets and 1 point per $1 elsewhere, capped at $8,000 per statement period.

Application friction for new customers

• New applicants report the online application crashing or losing entered data mid-flow, forcing a full restart.
• The pattern sits alongside the same platform complaints existing cardholders raise post-migration.

Start with self-service — it's the fastest fix for simple things

• Log in to the Online Service Centre or open the Coles Credit Cards app to activate a card, set or change an ATM PIN, temporarily lock a lost card, view up to two years of statements, make BPAY payments, check your Flybuys balance and update contact details.
• The app and Online Service Centre share the same login as your Coles account. If you've never created one, set it up through "Log in / Sign up" on the Coles site first.

Live chat — best for account questions

• Tap the chat icon inside the Online Service Centre or the app. Chat runs 8am–10pm AEST/AEDT, seven days a week.
• Chat gives you a written transcript. Save it — that record does real work if the issue later needs escalating.

Phone — for anything urgent or account-specific

• General enquiries, lost or stolen cards, suspected fraud: 1300 306 397.
• Calling from overseas: +61 2 8288 2890.
• Struggling to make a payment: 1300 194 546, Mon–Fri 8am–8pm, Sat 9am–1pm.
• Hardship arrangements: 1800 931 356, same hours, or email hardship@secure.coles.com.au.

Before you call

• Have your account number ready. Since 8 September 2025 it's different from your card number and prints on statements issued after that date.
• Call mid-morning midweek. Mondays and lunchtimes are the worst windows.
• Record the date, time, channel and name of everyone you speak to, and ask for a reference number even on a routine call.
• Screenshot app errors and failed logins. They carry weight later.

Put it in writing

• Use the Coles Credit Cards contact form when the matter isn't time-critical and you want a paper trail.
• Coles Credit Cards dispute a transaction form: lodge through the online transaction dispute form or call 1300 306 397. Mastercard chargeback windows are time-limited, so don't sit on it.

Lodging Coles Mastercard complaints

• Say it plainly: "I'd like to lodge a formal complaint and receive a complaint reference number." Ask for it to go to the internal dispute resolution (IDR) team.
• Under Australian financial services rules, the issuer must acknowledge your complaint promptly and respond in writing within regulated timeframes — generally 30 calendar days for most credit card complaints.
• Never let a card run past due while you wait for a fix. Pay by BPAY or at Australia Post, and keep the dispute running separately.

A credit card is a banking product, so the protections that apply are banking protections. Chargebacks, the ePayments Code and hardship law do the work that refunds and returns do in retail.

Disputed transactions and chargebacks

• This is the refund equivalent: unauthorised, duplicated, or undelivered goods and services can be charged back under Mastercard scheme rules.
• Lodge via the online dispute form or on 1300 306 397. Time limits apply, so act early.
• A temporary credit issued during an investigation can be reversed if the dispute fails. Several cardholders were caught out by exactly this.

Fraud and unauthorised use

• Report immediately on 1300 306 397 (or +61 2 8288 2890 from overseas), and lock the card in the app while you wait.
• Under the ePayments Code, customers who haven't acted fraudulently or unreasonably are generally not liable for unauthorised transactions.
• Guidance sits on the Coles Credit Cards Online Security Hub.

Cancellations

• You can cancel Coles Credit Card accounts at any time by calling 1300 306 397.
• Clear the balance first (or arrange a balance transfer) and cancel any direct debits attached to the card.
• Ask for written confirmation of closure. Annual fees on fee-charging cards generally aren't refunded pro-rata unless your terms say otherwise.

Financial hardship and payment difficulty

• Coles Credit Cards hardship assistance is a legal right, not a favour. Call 1300 194 546 for payment difficulty or 1800 931 356 for hardship, or email hardship@secure.coles.com.au.
• Support can include payment deferrals, reduced payments, and interest or fee waivers.
• The Extra Care Hub covers customers facing family violence, illness or bereavement.

Changes to rates, fees and rewards

• The issuer must give notice before changing your terms — current and recent changes are published as variation notices, including the changes effective 1 October 2026.
• If a change doesn't suit you, you're free to close the account.

Complaints and external escalation

• Lodge with the issuer first — by phone, through the Online Service Centre, or in writing to the address in your terms and conditions.
• A Coles Credit Cards AFCA complaint costs nothing and is open to you if no response arrives inside the regulated timeframe, or if you're unhappy with the outcome. Contact the Australian Financial Complaints Authority on 1800 931 678, at info@afca.org.au, or at GPO Box 3, Melbourne VIC 3001.
• AFCA membership is compulsory for the issuer, and its decisions bind the firm once you accept them.

Returns, warranties and price match

• None of these apply to a credit card account itself.
• For goods bought with the card, pursue the merchant first under Australian Consumer Law, then use a chargeback as your backstop.
