SBI — Fraud Transaction and lost amount

Address:

Lucknow, Uttar Pradesh

Today I got a call from [protected] and they told that they are calling from RBI. They asked to verify the card number and sent a OTP password. The OTP password was received on my registered mobile number +919XXXXXX. We confirmed the OTP as well. After that they have deducted all my account balance and only INR 200 is left in account. I lost INR 12282.28. I called on this number [protected] again and they seems to making fun of situation. They said that they are calling from “C Bharat Nagar, Kurla. Mumbai”. The worry part is that they can see the whole account information. I suspect if they can harm again. I have already got my card blocked. Please look into this issue and if possible make necessary investigation.
