I just called and left a message, or actually my TV did. I put the phone next to the TV. It doesn't let you record long though. Then I pressed number 1 to make it an urgent voicemail. I think I will do this everytime they call me.
Also receiving calls from this number, about two a day. Called it back and got a voicemail box. Left a message telling them to stop calling, so who knows what will happen next. No info on this number tho, other than they're from Michigan. GRR!
They purport to be a car insurance provider and have my home address. Don't know if it is a scam but I tell them I do not need car insurance. And I'm on a no-call list.
