Address: Manager, HDFC Bank Cards Division,PO BOX # 8654 Thiruvanmiyur PO Chennai - 600 041

Dear sir,
I had transaction by payzapp app. Through hdfc cradit card ([protected]) for rs 2474/- at grofer on dated 07/07/2020 but due to internet problem, amount debited in my hdfc cradit card account but payment is not received at grofer account. Failed transfection has been done. July’20 bill is also generated by hdfc cradit card but my amount is still not credited.
I have given several mails to hdfc customer care but have not get any proper responses.
You are requested to do needful action

Regards
Mohit gupta
