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.
