State Bank Of India [SBI] — Fake phone call to get sensitive information (Phone phreaking)

Address: Papum Pare, Arunachal Pradesh, 791110

I was targeted by a phone phreak. I got a phone call at 8:30 AM on 19th November, 2015, from the number [protected]. The person on the other side asked to talk to me about my SBI (State Bank of India) account without mentioning my name. I didn't had any SBI account so I asked him whose account is he talking about. He ignored it and told that my debit card has been blocked. Then I told him that I don't have any SBI account and asked if he was talking about my mother's SBI account. Then he confirmed that it was my mother's account, again without mentioning any name. Then asked about the type of debit card, maestro or visa card. I told him that it's a visa card. Next he asked the number that's printed on the card. That was odd. So I asked him if he is really calling from SBI. He tried to ignore but I asked it again and he hung the phone. I understood that it was fake. I went online and traced the phone number [protected]. I found that it was a GSM Airtel number from the region Bihar & Jharkhand. I could have been just one of the many targets of this attacker. Desired resolution: A resolution would be that the police or telco find out about the person and stop him from continuing such activities.
