Costco
customer support overview

Costco Australia provides multiple ways for members to get support: a Melbourne-based Member Care hotline, live chat on costco.com.au, and in-warehouse Member Services desks. The hotline (03 5316 7223) is open Mon–Fri, 8am–5pm AEST. Live chat runs during the same hours for real-time help with online orders, membership queries, or product issues.

In-store, Costco’s Membership Desk is a key advantage – you can resolve most issues face-to-face, including returns, refunds, and membership changes. Costco’s reputation is built on its generous returns policy and strong member-first philosophy, including their pledge to refund your membership fee if you’re ever dissatisfied.

Overall, Costco enjoys high customer satisfaction in Australia, particularly for its “no fuss” approach to returns and refunds, friendly staff, and willingness to keep members happy long term.

Common
Costco
 customer issues and complaints

 Despite a strong reputation, members report some recurring issues:

  • Online orders: Delayed shipping, poor tracking updates, and difficulty cancelling orders once placed.

  • Delivery coordination: Issues with third-party couriers, including missed deliveries or refusal to move large items upstairs.

  • Crowded warehouses: Long checkout lines and parking congestion at peak times.

  • Staff interactions: While many staff are praised, isolated reports mention rude or unhelpful service at membership desks or checkout.

  • Product quality concerns: Occasional issues with fresh produce or perishable items, quickly remedied by Costco’s refund policy.

  • Refund delays (online orders): Refunds can take time if an order is refused or returned via courier.

Most of these frustrations are offset by Costco’s robust returns policy and willingness to ultimately resolve complaints in the member’s favour.

How to contact
Costco
customer support

  • Phone (Member Care): Call (03) 5316 7223 (Mon–Fri, 8am–5pm AEST). Have your membership ID and order details handy.

  • Live Chat (Support Bubble): Available at costco.com.au during business hours. Quick for order status, tracking, and refunds.

  • Email: Costco Australia does not offer a general customer service email. Agents may provide one for attachments during cases.

  • In-Store: Visit the Membership Desk at any warehouse for returns, refunds, or membership help. Returns can be made at any location, not just the original store.

Tip: For complex warranty or service issues beyond 90 days, ask about Concierge Services, Costco’s tech and appliance support program.

Costco
key customer policies: refunds, returns, cancellations and more

  • Returns & refunds: Most items can be returned at any time if you’re not satisfied. Electronics/appliances have a 90-day return window. Refunds go back to your original payment method.

  • Membership refund guarantee: Cancel anytime for a full refund of your membership fee.

  • Order cancellations: Must be requested via Member Care. If already shipped, refuse delivery or return for a refund. No restocking or cancellation fees apply.

  • Price adjustments: No formal policy. Managers may refund price differences as a courtesy if an item drops in price shortly after purchase. No competitor price matching.

  • Warranty & after-sales: Costco coordinates with manufacturers and offers Concierge Services for electronics/appliances. If manufacturers fail, Costco will step in under ACL.

  • Shipping: Many online prices include delivery. Large-item couriers contact members to arrange delivery windows. Costco covers shipping costs for most returns.
