Skip if clearly fraudulent.

To file a Purchase Protection claim:
| Stage | Time |

| Merchant response window | 30 days |
| Final dispute decision | 45-60 days |
| Purchase Protection claim | 5-10 business days |
Yes - Amex provisional credit usually within 24-48 hours. Faster than most issuers. Reversed only if the dispute is denied with merchant evidence.
Disputes are for transactions you didn't authorize or merchants who didn't deliver. Purchase Protection covers items you bought but were damaged / stolen / lost within 90 days. Both can apply to the same situation.
Amex's business model values long-term customer relationships. They prefer to lose a small dispute than lose a high-spending customer. This is why Amex disputes resolve in cardholder's favor more often than other issuers.
Federal law allows 60 days from statement date for billing-error disputes. After that, Amex can use discretion - they sometimes accept older disputes for goodwill, but not guaranteed.
Other questions our readers commonly ask about this topic:
Yes - American Express customer service is reachable on a toll-free U.S. number that does not charge a per-minute fee. Standard mobile-carrier minutes may apply on metered cellular plans. International callers may pay long-distance charges depending on country and carrier. Visit our American Express contact page for current toll-free numbers and hours.
Simple problems (account access, password resets, basic billing questions) typically resolve in a single 10-15 minute call. Complex issues (refund disputes, identity verification, escalated complaints) usually take 3-7 business days because they need supervisor review or document submission. If your case has stalled past 7 business days, escalate to a supervisor or the executive customer service team.
First, politely ask to escalate to a supervisor or to the executive customer service team. Most brands have an internal "office of the president" that handles complex complaints. If escalation does not resolve it, file a complaint with the Better Business Bureau (bbb.org), your state Attorney General consumer-protection portal, and - for finance, telecom, or airline issues - the relevant federal agency (CFPB, FCC, or DOT). Our American Express customer service guide lists the alternate channels.
