This (person or company) keeps calling me so I finally put a trace on the number.  It is for a telemarketing company trying to sell 'credit card debt reduction' or whatever they are really offering.  When I pick up the line there is a recording saying 'hold on for very important news about your current credit card' and I hung up.  Then it calls over and over, same message, no number being given.  So I dialed ^69 and got the above number.

Left a message saying they were from my cable company offering an upgrade if I made arrangements for a technician to come to my house.  NO WAY!  I'm blocking them!
