Order id:[protected]. Honor 9lite received with a faulty battery. Hence request for replacement to amazon.in response, amazon informed that you have to send this mobile through your courier service. Hence i have sent mobile to corresponding address through tracking id: eg[protected]in indian post. Return order id:[protected]. At 30/07/2019, seller received this product return but didn't send it back to me. Hence after several follow up amazon representative told me that seller received a different product. I don't know why such fraud has been created by amazon seller & amazon. Please look into the matter seriously & solve my issue as soon as possible. Otherwise, i will raise a complaint against amazon into court & all social media. Even after 15 days, i didnt received any response. All reference document is attached herewith.
