What our Amazon customer service covers
A-to-z Guarantee claims and chargebacks
Each claim reviewed on time, with tracking, delivery proof and order history submitted, so you have the best chance of a ruling in your favour.
Returns and refunds
Return requests authorised or reviewed, refunds and replacements issued within Amazon policy and your rules, and return reasons logged so patterns are visible.
Negative feedback
Seller feedback monitored, buyers contacted within Amazon’s rules to resolve problems, and removal requested where feedback breaks Amazon’s guidelines.
Product and listing issues flagged
Repeated questions, complaints and return reasons fed back into listings, images and packaging, so the same problem stops coming back.
Account health and reporting
Response time, Order Defect Rate and return trends tracked, with a monthly report on volumes, issues found and what changed.

Why customer service matters on Amazon
Amazon measures how you treat buyers. Buyer messages are expected to be answered within 24 hours, including weekends and holidays. A-to-z Guarantee claims, chargebacks and negative feedback all feed the Order Defect Rate, which Amazon expects to stay below 1%. Slow or careless service can cost you the Buy Box and, in the worst cases, put the account at risk. Most A-to-z claims start as a buyer message or a delivery problem that nobody handled in time, so the cheapest claim is the one that never happens.
Within Amazon’s communication rules
Amazon limits what sellers can say to buyers: messages are for completing orders and answering service questions, not marketing, sending shoppers off Amazon or asking for positive reviews. We work from templates you approve, check free-text replies against Amazon’s rules and keep a record of every case. Access is granted through Amazon’s user permissions, which you control and can remove at any time. We never ask for shared passwords.
Service connected to listings and ads
The same team that handles your messages also runs listings, PPC and account health, so problems found in service get fixed at the source. If buyers keep asking the same sizing question, the answer goes into the bullets and images. If a product keeps coming back for the same reason, we flag it to you and look at the listing, packaging and instructions. See our Amazon return rate reduction, Amazon review management and Amazon account management services.
Compliance and account health, too
Customer service sits next to compliance. We also handle Seller Central cases, policy warnings, compliance documents and listing issues, so one team watches the whole account. See our Amazon cases and compliance and Amazon account suspension help pages. We cover every Amazon marketplace, including the US, the UK, Canada and Europe.
