Who called from 4072050307

4072050307 and 4072050229 are scam numbers.  When I called the back I got a recording that it  was from a "marketing research" company or a political organization but they did not identify who the company was or the political organization.  I am SO SICK of getting these calls!  There must be something that CAN BE DONE TO STOP THIS!

Calls constantly and hangs up.  Put them on the blacklist with an out of order tone, yet they still keep calling.

I have called this number back requesting to be put on their DNC list several times! They are a scam & a joke. They continue to ignore all my requests -- AVOID!
