Mobikwik, Billdesk, PayUMoney — Fraud transaction from SBI Debit account

Address:

Bangalore, Karnataka

I received a phone call from mobile number +91 [protected] at 8.30 am on 4/08/2015. An unknown person claiming to verify SBI card stated that he was calling from SBI main branch. He told me my 16 digit ATM card number and asked my card details and retrieved key information. After a few minutes, i started receiving SMS regarding ATM card transactions made for online purchases. This has been done without my knowledge and consent.
