I just got an "automated" phone call from this number.  They were advising that "nothing is wrong with your credit cards at this time, we are calling to give you a discount on the rates for your credits cards.  Please press 1 to continue to speak with a representative or 2 to disconnect this call'.  I pressed one and it was dead air, which I immediately hung-up on.  Hopefully I just didn't give the person who called access to my phone information by doing that.  But time will tell.  (I was going to find out who they were and tell them to bugger off and take me off of their list, but I didn't get the chance to do it).
