There's already a thread here under their other number, which also shows on caller ID as brown dirt mark:

I didn't answer and they didn't leave a message. Oddly enough the second they got done trying to call, I got a call from 801-618-4712, there's a thread here indicating that they are auto warranty scammers, so the numbers may be connected in some way.
