HDFC Bank — credit card

Address: Kolkata

Hdfc team,
I am saumya praharaj, hdfc credit card holder (Card no. 5241*5265), the last cheque was not cleared due to some technical issue but after that i have debited the last payment amount of ₹11, 000/- only (Eleven thousand) on 27.07.2020 through upi payment.

But then after the same amount of ₹11, 000/- only (Eleven thousand) was again debited from my account through the cheque on 28.07.2020.
I am continuously following this matter since 28/07/20120 and contacting the person owho was looking after this matter, but zero progress i found and last one week he is not answering my call and not even bothered.

Now i request you to reverse the extra amount of ₹11, 000/- only (Eleven thousand) which was debited by mistake asap.
