if no caller id... how do you know the number?????

I just  called  the ftc.gov and told them I get this 936-495-8708 TX number calling everyday yes the senior  meesage, when I finally  decided  to hit one to talk to a supervisor  they hung up! I called back and the number is no longer available  how if they keep  calling me and I went through  my phones memory  this number comes up with different  Texas cities ftc.gov says it's a scam, hope they do something  soon glad I am not the  only ones getting this call !! And I am 46! Ugh!

It's a scam call.  The scammers ignore all US laws. They ignore DNC.   Call blocker might be some help.

Selling some type of medical alert system - calls (minimally) on a weekly basis.  I am on the do not call registry (which is worthless)

I am repeatedly receiving unwanted calls from this number.  I have requested multiple times that I be removed from their calling list.  My requests have gone unheeded.   I have even tried to call the number back to request removal.  When I do,  I get a recording that indicates this number has been changed or is not a working number.  How can that be?  They keep calling me, but I can't call them back to get removed from their calling list?
