Amazon India — returned items not refunded

Address:	Pune, Maharashtra, 411006
Website:	Amazon india

I order 2 items in august 2018 and wanted to return them. After various conversations i was told i could return but i would have to send them by one of 5 courier serives that amazon recommended and i would have to pay the corier charge but this would be refunded once the items were received and i emailed the receipts. All of this was done bu 15.09.18. Since this time i have been asked to send copies of the receipts on various occations and aslo the proof of delivery from dhl. Since this time i have been contacting amazon customer service and i did actually get confirmation that the refunds would be given. It is now almost 5 weeks since i retrurned the products and each time i query this i am getting various emails for amazon either astating my complaint has been esculated and allow 3-5 days, some mails asking for the details again, i have actually got 2 mails yesterday telling me they are asking the seller of the product if they will authorise the return.in total i have around 35 mails around the subject and each one is a different respose.
Amazon confirmed 2 weeks ago that items had been received and now the latest email is saying that there is an issue with the proof of delivery. Im am owed approx 6000 rs for the products and 8000 rs courier charges. I have been promished over the phone that these will be refunded and also by mail. It seems i am right back at the beginning again with my query and after asking countless times for a management contact name, number and email this request has simply been ignored.
