Your consumer rights: the 60-day billing error rule
Merchants often provide fake documentation to fight automated app disputes. Here is the exact statutory leverage you hold when submitting a formal written notice to Citibank.
Federal statute — Fair Credit Billing Act (15 U.S.C. § 1666)
Under the federal Fair Credit Billing Act, card issuers are required to acknowledge and investigate consumer billing errors, which explicitly include charges for goods or services not accepted or not delivered as agreed.
The strict 60-day window
To trigger your mandatory federal protections, your formal written notice must reach Citibank within 60 days after the first statement containing the billing error was mailed to you.
Why this charge is disputable — Defective Merchandise — Retailer Refused Return
When a retailer publishes a return policy and then refuses to honor it, federal billing-error protections allow you to dispute the underlying charge as goods 'not delivered as agreed.' The published return policy is part of the contract, and breaching it converts the sale into a billing error.
Remedy
Full reversal of the charge, written authorization to dispose of or return the defective item, and confirmation that the dispute will not be reopened if the merchant later submits rebuttal evidence.
Evidence to lock in your claim
Save a screenshot of the retailer's published return policy on the date of purchase, the original receipt or order confirmation, photos of the defect, and the retailer's written refusal to accept the return.
Crucial tactic: Submitting a dispute via the Citi mobile app is convenient, but it does not always trigger your formal protections under 15 U.S.C. § 1666. Sending a structured, printed dispute notice directly to Citibank's dedicated Billing Error Address ensures your claim is handled by human compliance officers rather than automated filters. Citibank — Centralized Disputes: P.O. Box 6500, Sioux Falls, SD 57117 (verify on your most recent statement).
