Amazon India — Multiple pickup failures

I have ordered a backrest for my grandmother which we realised would not be helpful and requested a return. This was 21 July, and till now, 25 Aug, 7 times I had called customer care and requested pickup. Everytime i was assured it would be picked up for sure but no pickup is attempted, instead the pickup status is updated online as Package Carrier missing, hence, pick up failed. I do not receive any messages on mobile either that there would be a pickup that day.

It's been more than a month and honestly I am fed up listening to false assurities and seeing no action. Moreover, I would be calling them tomorrow, Aug 26, to hear the same thing again. Additionally, I am always told advance refund cannot be initiated as product must reach wharehouse first. Please explain to me why am I suffering when the product is ready for pickup, your job is not done and yet my money is on hold.

I implore Amazon India to please get their job done, and get the product I have packed and ready at the entrance, waiting for the delivery person, picked up.
