I missed a call from this # at 2:22pm today. They didn't leave a VM but I took a chance & called them back. On the phone they called (Tracfone) the call wouldn't ring & it said invalid # on my screen. When I called from another phone (AT&T) the # rang but wasn't a valid #. Tired of these phone games/scams on my Tracfone. It doesn't matter that I'm on the DNC list either.
