[Resolved]  HDFC Bank — Credt card payment

I Raja Inapakolla holding a HDFC BANK CREDIT CARD, I am in due for the amount of Rs.60, 000.00, i have payed the amount through cash payment to one of the employee Named K. Praveen kumar of Hdfc Credit customer care employee. (a sub division employee of ADFC (ATLAS DOCUMENTARY FACILITATORS COMPANY PVT LTD)). He is known person o[censored]s he used to stay in my house as a paying guest. suddenly after taking the money he vacated the house. From the day of paying i am checking my account for updation. Till now it was not been updated. As per the proof of given money i don't have any written evidence, but i have given in front of our friends to him.i have only oral evidence of our friends only.
He is not even lifting the call.And he is blackmailing that he is going to link up my savings bank account to credit card to withdraw my money from the account.

Another thing to say that the bank collection department is torchering & harassing me like any thing from few months.To whom i should approach to solve my problem.
