Mts, HDFC Bank — Fraud from credit card

Address:

Kolkata, West Bengal

A person named Avinav (ph. no: [protected]) called me up and mentioned that I had a lot of points in my credit card to be redeemed. Then he asked me to verify the credit card number and then he did some transaction by which I got an OTP from the HDFC bank and he asked me to type the same from my phone. Then he debited rs 7999 from my account in the name of gifts8home_payTM MUMBA. When I investigated, I found the phone number from MTS Delhi NCR. I am surprised how a company like MTS is not doing any KYC while providing SIM card. How come a person who can do an open online transaction from a site which has no registration. HDFC has no clues about this although it has been happening since long. I have no idea how to sort it out. But I will fight till the end. Regards, Sambit.
