By Phone long history short --- Long time ago a friend of me told me once he received a call from his bank (fake) asking for some information and telling him about some irregular transactions, he got scare and told them he will look after this information. He checked his bank account and got a messages that someone tried to enter into his account so that freaked him out even worst. Finally they got another call from the same agent from the bank (fake) and he gave them his information to fix the problem. after this call he recieved again a call but in this time it was for the real bank telling him that they detect someone tried to do a transaction with his resources so they stopped to confirm that was real.
