[Resolved]  HDFC Bank — refund not received

I have provided all the possible proof and details of refund still the bank have not credited the amount in my account. Please look into the matter.
On 4th april 2020 i received refund of rs. 8170/- in my credit card but the same is not reflecting in my account.
Arn number of refund is as follows

Acquired reference number: 75503720096039297964215
Arn is the proof that payment has been made and it is passed to the bank.

Screenshot of transactions are attached as the proof that amount has been reversed but not credited yet.
I have been ignored since last 25days, hope to get the status of my refund this time otherwise i will just block my card and shutdown my & my family's account from hdfc bank. If you can not help your customer in this crucial time then what can i expect from you.
