they are cheaters it seems. I complained to ICICI disputes team and they are of no use as they just say they cant help as it is a secured transaction as we spell out OTP numbers, but the problem is they pursuade in a way that they are from ICICI and they also have all the information about card,points existing and the last transaction done. We should register a complaint against these guys and also ICICI. I did save the numbers from which I got the calls. The problem is also if we go to the police they wont even bother to look into this as they are cheaters themselves.
