On any Amazon product page or order, look for "Sold by [seller name]". If it says "Sold by Amazon.com", the order is direct from Amazon - skip this guide and call Amazon customer service.
If it shows a different seller name (e.g., "Sold by ABC Store"), it's a Marketplace seller. The seller is responsible for shipping, returns, and customer service - though Amazon ultimately backs you up via the A-to-z Guarantee.
Sellers are required by Amazon policy to respond within 48 hours. Most respond same-day.
Amazon Marketplace policy requires sellers to respond to buyer messages within 2 business days. If you haven't heard back, you have grounds to file an A-to-z Guarantee claim.
Return to Your Orders, click Problem with order > File / View Claim. The claim form will ask: what went wrong, what you've already done to contact the seller, and what resolution you want. Amazon usually decides within 7-14 days.
Amazon's A-to-z Guarantee covers virtually every Marketplace order against:
The guarantee covers up to $2,500 per claim with no fee.
If your A-to-z claim is denied or stalled, call Amazon at 1-888-280-4331. Phone agents can review and override claim decisions in some cases - especially when you have screenshots of the seller's broken promises.
Be polite and concise: "I filed an A-to-z Guarantee claim on [date] for order [number]. The seller hasn't responded in 5 days and the claim is still under review. I'd like to escalate."
48 hours under Amazon's Marketplace policy. After that, you can file an A-to-z Guarantee claim.
Yes - the A-to-z Guarantee makes Amazon the backstop. Most claims are decided in the buyer's favor when documented properly.
Yes - within 90 days of the order. Negative feedback affects the seller's metrics and can lead to suspension if patterns emerge.
Items shipped via Fulfillment by Amazon (FBA) are sent from Amazon warehouses, so customer service is mostly handled by Amazon directly - call 1-888-280-4331 first.
Other questions our readers commonly ask about this topic:
Yes - Amazon 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 Amazon 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 Amazon customer service guide lists the alternate channels.
