The FTC is very well aware of the problem:  Just yesterday there was a long news item from a major news agency about the fact that the FTC can't do anything right now about spoofed calls, because of the limitation of their own technology.  There is a growing movement by some Senators and Congressmen/women to have pressure put on telephone companies to protect their subscribers from this abuse.  It's not easy to solve.  But the authorities are aware of it, and while I too have been suffering from this same thing for months now, I am sure that in time they'll find a solution.

Once a day, every day - totally UNWANTED calls from this robo call number. How do I block it?

Please call the FTC to file a complaint.Famous last word's

Thank you for the FTC phone number

Constant calls from "Texas call" on caller ID 1-936-495-8708
