Amazon India — Complaint for refund

I have returned the watch on 29 September'22 to the delivery partner and he is saying he has submitted in the warehouse but in their tracker it's not showing submitted. I call on customer care and register the compain regarding the same on 30 September '22 but it's 1 month my reissue is not resolved yet.. I have call multiple times in the customer care for the issue but they always say that on backend it not showing give us 7 days time but it 1 month I have wait but the issue is not resolved. Even in the mid when I talk in the customer care they said and share a mail of refund initiate but after 7 days when I call they told me that refund is not initiated yet they send the mail by mistake.. In this time I have talk 7 executive and 2 head none of them are helping me they are just saying it will be resolved within 7 days, backend issue.. but I have wait for 1 month. This is very disappointing that I have to wait for my money for 1 month.. none of the customer care are comparative. If the issue is from backend so they have to take issue on priority but every time they raised the complain again and again and ask for 7 days time now I am fed up with this thing..Requesting you to kindly resolved it asap
