Who called from 3155338221

no one on the other end.  They just hung up.

Probably spam.  I get tons of spam calls for some reason...I answered and hung up right away.  This number is going on my blacklist.

They call so I call them back it was about my vehicle warranty. I told them I have no vehicle so they hung up on me I knew it was scam

They say they are with a company called Car Protection USA regarding warranties

Called to update me on car warranty which was due to expire soon.  When I asked which car (vehicle) she indicated that was a good question and would get specialist.  She again ask how vehicle was running and I wanted to know which one...she hung up
