Amazon India — Mental harassment

I bought a ladder from Amazon amd it was delivered on the 17th October 2022. I made a return request on the 20th and no pick up was made. I got a msg from them on the 22nd that the pick up wud be done today..I got calls from pick up agent asking is it a big product and when I told them they said van will come to pick but no one came. But it was not done. On 23rd the same thing happened and pick up was not made. I called the customer care 31/10/22 at 5.45 pm and I was told that it is under verification. I asked her and she said that your prod doesnt match, but I told her that when no one came how can anyone put it under verification. she said she is removing it from verification and it will b picked upr by 7 pm today. But it was not picked up.
I got a pick up msg on the 3rd but no one came. Then I called the cutomer care again on 4/11/22 at 5.14 pm, 5/11/22 at 2.31 and on 10/11/22 at 2.10 pm and everyone told me tehy are removing the verification and it will b done. I got the pick up msgs on 8/11/22, 9/11/22 and 11/11/22 but no pick up has been done. This is ridiculous they are fooling around. Amazon has bunch of irresponsible agents who are not happy to help. They have harrassed me so much. Some has to be home to get the pick up done and nobody comes for it. They have mentally harrased me by everytime giving me false details. And creating a wrong verification huddle for my pick up. I have cctv at my place and can show that no1 from amazon came to pick up so how come it got pending for verification. I have all the call recordings and also the msgs that I have recvd from Amazon. Their customer service is a harrassment
