My wallet was stolen and a woman called from this number saying she was from my bank.  Feeling very vulnerable I divulged my pin number after she had told me money had been taken from my account.  She asked if my pin number would've been written anywhere and I said no and told her what it was referenced to.  It turns out that probably no money had even been taken at that point.  When I got home and looked online, another 200 dollars had been taken out on top of what the woman said was taken.  It would seem this woman and the man who stole my wallet were working together.
