Got a call from this number, cid was Pontiac MI. Didn't answer as I didn't recognize. No message from caller, just a dial tone and then a message from the phone co. Saying if you want to make a call please hang up and try again.  Seen this before on robo calls. Got a similar call yesterday. Only difference was that# was 9457 instead of 9180. Seems likely that they are scammers.
