My amazonseller id is [protected]@gmail.com i am a seller over there. Customer ordered me wifi dongle and i delivered through dtdc courier and mentioned tracking id in amazon as their rules. Customer received the product on 22 dec and delivery time was till 24 dec. But customer sent me mail through amazon that he had received product late on 30 dec and he dont want the dongle but i cancelled his request and sent him dtdc courier tracking id and screenshot that he had received the product on 22. After that he again mailed me same 2 times and i reverted him again with all proofs. Amazon had written in their claim policy that if seller did not respond to buyer then they will check the matter and reffund the money to buyer if they found buyer right. But in my case they did not checked my reverts to buyer with proofs. They said me that they had sent me one mail which i had not reverted thats why they reffunded the money. But what about that mails which i had done from your amazon id to customer with all proofs. I checked your policy on 6 jan there was written that if i did not reverted to a to z claim mail in 7 days they will refund my money but my money was refunded in 6th day. Then i talked on chat witj customer care and told about this he aggreed and said plz talk to our team . When i talked to team they said we cant do any thing and changed their policy from 7 days to three days. If you are refunding money to liers without checking seller revert to customer then why are you saying that customer can file a to z complaint if seller dose not respond Even I had responded 3 times.
