Who called from 8472328781

Gmc auto scam. Operator hung up on me mid sentence

This group continually calls and hangs up to a cell phone.  I believe they are trying to sell me a policy for a car that I sold 6 years ago.  They are annoying and I have tried to block them

Same as the above. They are trying to sell me an additional warranty for a car in my possession that still has a warranty.  Put on the auto reject list.

This number continually calls and no one is on the other end.
