[Resolved]  Canara Bank — Online banking fraud

Address:

New Delhi, Delhi

Am writing this on behalf of my 64yr old retired mother who lives in Delhi. A few days back she got a call from some person who said he is calling from Canara Bank and that her debit card is deactivated. He mentioned all the information to her regarding our accounts, numbers, address etc which was all correct and she believed it was a genuine call from the bank. He asked for the CVV number at the back of her card and my mom has never done transaction or payment online and she didn't know how important that is for the online transaction. As soon as she gave out that number the call got cut and she started getting message alerts from the bank of the debit transaction done. She quickly went to the branch and narrated her incident, the bank people stopped the debit card but still we lost over 18thousand. She also submitted an FIR regarding this but even the police say, your money cant be returned back. My question is doesn't the bank have authority to reverse transaction when they know its a faulty one. Am clueless as to what can be done now, please if anyone could advise any procedure to follow would be of great help!
