Got a call, it wasn't a familiar #, so I didn't answer.  No message left. These calls seem to be more frequent, so I figured I should start looking up these #s and posting, in case, like me, these posts will help others.

REPORT THEM TO THE federal trade comission and to your cell carrier.  ESP ones that ask for credit card number!!!!

I also save them on my cell:  I give them the name "SPAM" so I won't accidentally pick up AND I set the ringer to SILENT so I won't even know they are there till I look.
