Be careful. This number showed up on my mobile caller ID and woman claimed to be from NAB security dept. She knew my name. A lot of background noise (like a call centre) but her accent was Indian (of course it was).
She then proceeded to tell me she needed to speak to me about my NAB acct . I said what is the problem (without divulging if i even had an acct with NAB) and with that she hung up. Can only assume it is all part of a scam from these low life people
