On 26th august 2017, I got 6 transaction messages from sbi card with AUD detections of 100's and 50's . I got a call from sbi that your card is been hacked and since it is blocked. How come this would happen with sbi. These transactions are made without my knowledge, no otp or pin.How could we trust using crddit cards online if this is the case. kindly look at the issue and provide solution. I am very much worried and the transaction disputes for more than 27,000 INR.
