Subject charge dispute refund never processed

Dear sir, mam

A refund of 4970. Rupees was successfully processed on 16 december 2019to my account. This amount should have been credited to my union bank account by now, but i have not received the refund till now. My refund reference no is[protected]

I have called the union bank of india customer service and also emailed the union bank of india main branch all the details many times including the unique transaction reference number but nobody has replied or resolved the problem. No action is being taken...
But, the refund has not been received yet.
Bank is saying no amount has been received by them. I have talked to them again and again but no responss is coming. So i need to file a charge dispute on them, to get the full details.
I need bank to resolve this issue as soon as possible or i'm gonna take some legal action.

I have confirmed with amazon and they have successfully processed the refund

Kindly go through the charge dispute emails, locate the pending refund and follow the path back to amazon payment processor to locate the refund.
