Amazon India — Not Picking-Up the product and not initiating the refund.

Dear Sir/Ma'am,
I placed an order from @Amazon Indian on 24.02.2023 which was delivered on 03.03.2023 but due to the issue in size on 04.03.2023 i placed a return which was aprooved on the same day and the pick-up was scheduled for the next day i.e. 05.03.2023 but the product was not picked up from my home, yesterday when i tracked the return status it was showing me that the Pick-up was cancelled now it is also not shpwing me the option to place another return, the return time period will end on 13.03.2023 after this date amazon would not return my order and refund will not be processed. I have also sent a mail to amazon 2-3 time but they are not replyong amd only givigng and automate reply that we will rvert you back within 6 Hrs but no such action is placed.
So, it's my humble request to please look after this matter because after 13.03.2023 tthe return policy will be eneded.
