You do not have to absorb the cost of a scam, unfulfilled agreement, or product not as described. Under federal banking regulations, you have the right to challenge inaccurate or unfulfilled transactions directly through your card issuer. Use our software utility to generate an official Billing Error Notice that forces Citibank's compliance department to investigate and credit your account.
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 — Product Not as Described
The Fair Credit Billing Act covers goods 'not accepted upon delivery' and goods that are not as agreed. A counterfeit, broken, or misrepresented item is legally the same as no delivery at all. The merchant cannot escape liability simply because a package arrived at your door.
Remedy
Full credit of the disputed amount, written instructions for returning the defective product at the merchant's expense (if applicable), and removal of interest charges accrued during the dispute.
Evidence to lock in your claim
Photograph the item next to the listing description, save the original product page or screenshots, document any communication where the merchant refused a return, and retain shipping packaging if the product was damaged in transit.
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).
