Call from this number. No callerid, no VM.

They called and left no voice message.  Don't know anything about them other than their telephone number.

Called and left no message.

A different person keeps calling me from this number asking me to renew my warranty for a Buick. I have never owned a Buick in my life. When I tell them I'm not interested in there scams, they quickly hang up. Every time I call them right back to see if this is a legitimate number, I get a recording saying the number is no longer in service. There should be a federal regulation against scam calls. I get scam calls every day all day. It's ridiculous!!!!!!!!!!!!
