[Resolved]  Axis Bank — Loss of money from these diallers

I am getting calls from these phone numbers, saying axis bank credit card verification department. They say the availability of reward program and cashback offer along with gift packs for credit card holders. They continue the conversation even after saying "not interested". Also, they ask for confidential details about the credit cards (Card number, validity date, cvc etc).
I lost rs.8505 during the first call unknowingly. But, i am getting these type of calls frequently.
These are the phone numbers from which i am getting the calls (Involving in fraudulent activities)
