It's Medical Alert scampers  they call 2 x a day and will not give up.  do not answer "John" the robot will give you a whole song and dance about a delivery that has been prepaid and free shipping!  Yeah.  It is $37.00 per month for "maintenance" and they want a cc.  Despite that I intentionally answered one and spoke to a young lady (what a pity that you have to resort to work for a living in that manner) and informed her to remove me from their data base........yah!  What a waste of time and effort to keep calling.  What part of "NO" do they not understand.  I have them blocked on my phone, am on the "No Call" Registry and still get these calls.  STOP IT FOR ONCE AND FOR ALL. .
