HDFC Bank — illegal transaction

Address:

42/9,N Block Umapathi manson, kalappatti, Coimbatore, Tamil Nadu, 641014

On 23rd may 2019, suddenly i got message like transaction successfully done for ₹1044.43 with code with mose. I have dropped disputed form in nearest branch which is keeranatham branch, coimbatore itself. They told like within 5 business days it will get resolved.. But i didn't get any response from bank..

Again 23rd june 2019, i got same message like transaction done ₹1043.25 with code with mose. I got surprised.. I have called to customer care service and blocked my card. Got new card. I have paid all outstanding amount on 05th july 2019.

Frequently i'm getting message for otp.. But i didn't share my card details in anywhere.. Even i'm getting otp for transaction for my new card too..
