Amazon India — Toshiba C350NP 55 inch TV

I had ordered toshiba 55 inch TV from Amazon. I got delivered it on 7 dec. On delivery I got it damaged. So I immediately raised refund on return request. First amazone employee said it will be picked in next 72 hours. After 72 hours I waited for 24 hours extra. After that I called customer care once again an asked what happened about return he said your return is not picked up yet so I cancelled it. He cancelled my pickup on is end without my concern. Then I requested him to raise return request once again. He then contacted to his senior team. There I talked to a lady he then added return request once again. Also told me it will picked up in 72 hours. But 120 hours passed till yet no one came to pick up my return parcel. Amazons delivery partner and pickup partner is so lazy. Please help to resolve my issue I have to fill the emi if my item was not returned early.
