How to submit a complaint with
Citibank
 

Filing a complaint with Citibank Australia is straightforward, and you’ve got multiple options to choose from.

Online (fastest option): Use Citi’s official complaint form. You’ll be asked for your details, the type of issue, and the outcome you’re seeking (refund, correction, apology, etc.). Once submitted, you’ll get a reference number and Citi will begin reviewing your case.

Phone (24/7): Call 13 24 84 in Australia or +61 2 8225 0615 from overseas. Let the representative know you’re lodging a complaint and note your reference number for tracking.

Email / Mail: For escalations or supporting documents, email Citi’s Customer Relations team at aust.customeradvocacyunit@citi.com, or post your complaint to GPO Box 204, Sydney NSW 2001.

Accessibility: Citi supports the National Relay Service for the hearing impaired and can arrange interpreters for non-English speakers.

📌 Tip: Be clear and factual in your complaint. Keep copies of forms, reference numbers, and call details - these make escalation easier if needed.
