Dear Sir,
This is Ankit khamesara & my A/c no is[protected]. My credit card number is [protected].
credit card fraud has happened with me (04-sep-2021), for which your entire bank is responsible because the first thing is that I got the call from canara bank's toll free number, 2nd mistake of canara bank when my credit card balance is only 400 ya 500 If I had money, suddenly how did the balance come in my card, that too 49700 and after the fraud, the limit went back to zero, I am requested that the balance of my credit card which has been deducted, the payment should be added back to my card.Where do hackers bring all these details, in this the data must have been given from canara Bank itself and canara bank does not even show my credit card transactions, but my credit card statement shows all the transactions, just canara bank. does not show in the system
