[Resolved]  Ebay.in — long delay in refund process for defective product

I ordered "hd-hynudal hdmi karaoke mixer: two wireless mics: yamaha chipset" from ebay which was delivered on 7th august (Item number[protected], paisapay id [protected]).
The product was found to be extremely defective, with one of the mike producing erroneous output and other one not working at all. I raised a claim for return on 19th aug, 2017 and the very next day got a message from the seller that he will process the refund as soon as i ship the item back to him and he receives it. But this refund has to go through ebay channel.
Hence i immediately contacted ebay customer care for this process. To my utter shock, they rejected the claim for absurd reasons. Since then, i have contacted customer care atleast 6 times (On chat and on call) and everytime they tell me that my refund will be processed but i can ship the item only when i get a confirmation call from their side. They always ask for a time span of 72 hours for this, but i haven't received a single call till date. When i called and warned them of action the last time, they again gave an assurance that the very next day the claim team will call me to confirm the return process, but as usual, i didn't get any call.
This has frustrated me to the core, since the product costs a hefty rs 8950, and in this case even the seller is agreeing to issue a refund, but ebay is unnecessarily playing spoilsport and delaying it. As a customer, i am deeply fed up of ebay's product quality as well as return policies, and now i am fully aware why amazon has thrived so well in indian market, leaving these lame companies far behind.
