HDFC Bank — No otp .. bank involved in fraud

Address: Gaur cascade , Flat no A607, Rajnagar ext

Without intimation debitred from my account no [protected] of rs.1899
Rs-1899 debited from my bank account without my intimation on 31 st Dec around 6 -6.30 by the name of cponeassis & rs-1899 has been debited from my account without any pin or otp no. I am really shocked how does it possible. Without involment of bank .. I maid a complaint to hdfc and they refused to refund the same, that shows how all fraud is going on, I did not used any service or demand for it. Then how does these transaction done? I am not interested in this kind off services. So i request you to revert my debited amount in my account, otherwise i will go through legal against your company

Thanks n rgds :
