In the last two weeks I have received numerous calls from "unavailable". The calls will remain open with silence until I hang up. Verizon's official position is that there is nothing they can do to identify the caller. I really don't care who is doing this, but feel there must be a dept. that can contact the caller and ask them to stop. Anyone know how to cut through red tape on this one? I have recent data on exactly when the calls occurred.
