They call constantly! When you try to call back, you get a busy signal. There is no vehicle under my name and number, so I know it's a scam. I am reporting them everywhere. I am considering reporting them to the FBI.
Called my cell phone and my work phone- called back and some guy asked if I would be interested in car warranty- I said no I would like you not to call me- and he hung up.
It is no doubt a scam.
Save yourself some trouble, if they're calling your cell phone put them on the rejection list. They won't bother you again. This is the first time this number has called me and it will be the last.
