State Bank Of India [SBI] — Illegal withdrawl/ use of debit card using details

Address: 743123

Today ( 25.11.15 )I have received a call from [protected] from an unknown caller who identified himself as a bank official working with SBI Head office, Kolkata and asked me for my debit card details on the pretext of releasing my blocked debit card. On suspicion, I checked my account transaction after some time and found the entire amount of INR 4500.00 already transacted ( debit card purchase ) on the same day. My SBi account number is [protected] and my home branch is SBI, Naihati. Is there any way by which the culprit can be traced by using the transaction history, mobile number call details etc? I would also request a refund of the amount. Regards
