Who called from 3235559999

The message left isn't new; but, this is the first time for this number.   The incoming message sounds like it was pre-recorded and always indicates that it is related to the financial stimulus and that this is the last opportunity to take advantage of this offer.

Card Services scam. Update your block lists.

they call at least twice a day. How can I stop it?

I should have recognized that looked like a bogus number.  Picked up.  Record message with "important information about your credit card."    Hung up.

called, but left no message - weird number
