Please turn these people into the FCC. They have no right to call from a number no one can reach. Nor do they have the right to call and not respond when you answer. These kinds of people need to be fined to the MAX!! Maybe that will put them out of business if they are sued often enough!
This number calls often, I don't normally answer, however I tried to call back today just for the heck of it and the operator said this is not a valid number. I'm on the do not call list.
