Got a call on my cell from this number. When I picked up, it was a recording that said, "I'm sorry, that is not a valid selection, please choose another selection." Then it hung up. Blocked.
This number called me and the person on the other end demanded my social security number or they would send killer brainwaves through my phone next time I answered it. I left the phone off the hook while I fashioned a tinfoil helmet to protect my head then told them to bite me.
