Amazon India — Not refunding the amount and not picking up the cheap product

I have ordered Aristo plastic multipurpose container on 23rd July 2022, due product cheap quality I have requested for return immediately, but they didn't picked up the product. I have called the customer support and requested to schedule new pickup date and refund the amount, but no one responded. today I called Amazon for 5th time to request for refund but still they are not able to do it and asking for another attempt. They are keep on raising attempts to pickup but no one is coming to pickup. Please help on it.

Thanks.
