Xenon ValueServ_Paytm — fraud transaction in my SBI acconut

I am C.Subramaniyan residing at the above address. I have one saving Bank Account NO: [protected] at State Bank of India, Chettikulam Branch, Perambalur (DT), and Tamil Nadu. During February 2015 ( may be 08.02.2015), I was received one mobile Phone call from unknown person to my Mobile NO: [protected] regarding my saving bank account. He was told to me that “ I am speaking from State Bank of India, Chennai head office, Your Account number is [protected].Your ATM was in blocked condition due to no transaction for the past six months hence tell me your ATM card number, I am realize your ATM card and then only your are operate your ATM card” . I believed that person for telling of my Account number and name. As I am a illiterate and unknowingly I disclose my ATM Card number to that person. After that once again he was called to me and told that your ATM card was released and deposit some amount to your account. In the mean time, my co brother deposit Rs 50, 000/= (Rupees Fifty Thousand only) on 06.03.2015 in my Account for settle his Loan amount at my Native place. I went to SBI, Chettikulam on 09.03.2015 for withdraw the amount from bank but no amount in my account. I got a Bank statement and learn that the whole amount of Rs 50, 000/= was misused (POS Transaction) by somebody using your Website on 08.03.2015 and also the amount of Rs 1300/= was misused on 10.02.2015. I am a very Poor person, illiterate and suffering very much for the theft of Rs 50, 000/= thro your website. Hence I humbly request you sir, necessary action may kindly be taken for recover my amount from the culprit and handover the recovered amount to me please.
