This number, 08140915386 called me today, stating that he is calling from my bank and needs to revalidate my account and BVN. He wanted my correct date of birth. The scammer asked for My DOB too, then went ahead to call two dates in which one was my DOB. He wanted my card details too. Glad, I spotted he was a fraudster and made jest of him, and he immediately began to rain curses on me. Beware of this mad man.
