This caller is very persistent.  Almost every other day for the past few weeks they have been calling me from this and several other numbers (most I have blocked, I will also block this one).  Calls start at 9AM or a bit earlier, and come as late as 9PM.  Caller ID says "March of Dimes."  Does that organization still exist?  I thought March of Dimes was created during Depression Days to raise money to fight polio.  A very worthy cause to be sure, but isn't polio virtually wiped out now almost worldwide?  So why is this organization still looking for donations?  Why is it still in existence?  Sounds to me like this has to be a scam call.  That's why I block any number with an ID of March of Dimes.  Don't fall for it!
