Its the American Red Cross calling. Someone you would last expect to harass you with non stop daily phone calls. Its ridiculous. The person calling has to be making some kind of profit/kickback off of getting someone to come in to give blood. This should be illegal.
Your callers have no affiliation with 800notes. We can't do anything to stop the calls. Consider maybe getting a call blocking device or phone.. You can google them and many are around $60.00 or so.
