Several times a week I receive a robo-call from a Verizon number (406)852-8255 about which google knows very little save for other people with the same complaint. The call comes in to my mobile phone, but the robot never leaves a message and when I do answer, it hangs up on me.
Last night at 10:42 I got one of these things.
What's going on? They're not trying to sell me anything (or if they are, their robot is malfunctioning).
