Who called from 4072050249

I get phone calls from all sorts of numbers!! I am sick of it. I  won't answer my phone in less I know I know who they are because of these calls!!!

Collars from unknown source. They are bad calls. I will not  even pick up my phone if I don't know who's calling me !!

Numbers that have called me that I do not know who they are and if I pick up it is either trying to sell me something or telling me I owe something etc.

I get spam callers daily.  Just got this one.  Did not answer, message program picked up but only silence.  Computer generated caller.
