The short answer: a denied chargeback is rarely the end of the story. Behind the scenes, the merchant may fight back (representment), your issuer may push again (pre-arbitration), and the card network may make the final call (arbitration). You do not file these stages yourself — your issuer does — but what you send your issuer at each stage decides whether it keeps fighting for you. And the parallel paths (a CFPB complaint, small claims court) are often faster and more useful than the network ladder itself.
Stage 1 — your chargeback. You file with your issuer, which sends the chargeback to the merchant's bank. The merchant can accept it (you win) or fight it.
Stage 2 — representment (second presentment). The merchant sends evidence back through its acquirer: proof of delivery, your authorization, the cancellation policy you agreed to. If your issuer accepts the evidence, the chargeback is reversed and the money comes back off your account — this is the moment most people experience as “my dispute was denied.”
Stage 3 — pre-arbitration. If your issuer is not convinced by the merchant's evidence, it can file a pre-arbitration case — in plain terms, a second chargeback, saying the representment did not answer the claim. The merchant's side must then accept liability or decline, forcing the issuer to either drop it or escalate.
Stage 4 — arbitration. The card network itself (Visa or Mastercard) reviews the case and makes a binding decision between the two banks. The losing side typically pays arbitration fees, which is why banks only take strong cases this far — and why your issuer needs new, strong material from you to justify going.
These windows come from network guides summarizing Visa and Mastercard rules; your issuer will not show you this calendar, and individual processors may apply shorter internal deadlines:
For you, the practical deadline is much simpler: respond to your issuer's request for more evidence immediately. If your issuer is weighing pre-arbitration, a slow reply from you can be the reason it drops the case.
American Express is both issuer and network for its own cards, so there is no separate arbitration stage in the Visa/Mastercard sense. Amex reviews disputes internally, typically on roughly 20-day response cycles per stage, and its ruling is final within its own process. If Amex denies you, the network ladder is closed — which makes the parallel paths below your real next step.
CFPB complaint. If the investigation itself was mishandled — evidence ignored, deadlines missed, no written explanation — a complaint at consumerfinance.gov/complaint forces a company response (generally within 15 calendar days, with a final response within 60 days). Use our CFPB template.
Small claims court. For a merchant that will not refund you, suing the merchant (not the network) in small claims court is a separate legal route with its own deadlines and limits — see our small-claims guide. Check any arbitration clause in the merchant's terms first; some contracts require arbitration instead of court.
Regulator complaint (UK). UK readers have a different ladder: complain to the firm, wait up to 8 weeks, then take it to the Financial Ombudsman Service within 6 months of the final response — see our FOS guide.
No — arbitration is a dispute between the two banks, run by the card network. Your role is to give your issuer the evidence and reasons it needs to take the case forward, and to ask it, in writing, whether it will.
Months. A case that goes from chargeback to arbitration can easily run two quarters, with 30–45-day stages and a short filing window at the end. That is why the parallel paths (CFPB complaint, small claims) often resolve things sooner.
Generally the losing side's bank, and the fees can run into hundreds of dollars — one commonly cited Mastercard figure is around $500. You do not pay network arbitration fees directly, but the fee risk is a reason banks only escalate cases they think they can win.
Not necessarily. Your issuer may still file pre-arbitration if you supply new evidence that answers the merchant's case. Ask your issuer what it received from the merchant and what would change its mind — then supply exactly that, fast.
