This number kept calling me all day and I finally answered, and they said " Your bank account has been frozen!! Please call us with your bank account details and numbers!!! Beep!! So I tried to call the number back, but  it was not a existing number??, but from me calling them back, they text me a message from this number?? Saying to call them right away! OK,I'll get right on that!!  LOL. ANYWAY,I believe that you are going to be ripped off by these scums, so be careful.
