Who called from +44 7742 113246?

This number called me about a £600 debit from my visa card. An man with an Indian accent asked me for my bank sort code I asked which sort code and he said the one from my visa debit card. I told him I did not have a visa debit card and asked him to explain further. He hung up. Please be aware never to give any bank details out over the phone. If someone calls you about an unauthorised transaction they should already know all of the details. It is always best to hang up and phone the bank yourself.
