This is a particularly nasty robo call. I didn't pick it up and it left a silent message using up 4 minutes of my cell time. I called back to find out who they were and got "This number is invalid". How do lowlifes like this get away with it?
Caller did not identify himself or company he was supposedly with. Instantly started rambling in broken English asking if I knew something about my Microsoft security software and/or computer not working properly. Promptly hung up on some very strange sort of scam.
