Subject: charge dispute "refund never processed"

Dear sir,

A refund of rs. 193.75 was successfully processed on 12 march 2020 to my account. This amount should have been credited to my sbi account by now, but i have not received the refund till now.

I have called the state bank of india customer service and also emailed the state 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

I have confirmed with amazon and they have successfully processed the refund. They have given me a reference number which is as follows-
Ref. No.[protected]

Kindly look into the matter and resolve it as soon as possible please.
