IndustryBuying.com — Received defective product from Industry Buying and unable to get my refund

Address:

IB MONOTARO PRIVATE LIMITED Khasra No: 401, 402, First Floor, Ghitorni, Delhi - 110030

I have ordered one office chair from Industry Buying .
Order No. : #[protected]
The chair is tilted on one side so I cannot sit and do my office work. I have requested for refund to which they showcased that they have initiated the return. They asked me to fill very lengthy form. I have filled the form as well.
After many days of continuously follow up through emails and phone, they told item cannot be returned as we have initiated the return and pick up person said that you are not picking your call. I haven't received any calls from anyone of them.
This has happened with my previous order as well around one year back. I thought of filing case back then as well but due to Covid, I didn't do so.
This time I am not leaving them. It is a selfish organisation and doesn't seek any customer satisfaction. The problem customers face, it does not care.
