I got a missed call message this morning, blocked the caller.  The problem is that I receive multiple calls daily from different numbers about a vehicle warranty.  It is impossible to block ALL of the numbers and because it is a recording, you can't ask them to put you on their "do not call" list.  Next time  Ijust might wait it out until I get to a live person and then ask them to stop calling.  Between them and the numbers that are constantly calling trying to sell me a medic alert bracelet, it is a wonder anyone else can get through on my phone!
