this # was on my caller id a few times -- shows as a local # I called back (using call id block on my end) and they said it was discover card?  my bill is not due for another 2 weeks.  i did not give them my account # -- told them to call back and leave a message if they want to talk to me about my account

I'm beginning to answer these numerous calls just to find out who they are!!  This is someone from Discover Card.
