This is a scam. They are after personal information . Report and block number. You can also take action if they continue to harass you after you ask them to remove you from calling list. They called me over and over saying they represent Mercedes , have reported to corporate Mercedes Benz .
This company misleads you into thinking they are your warranty company for your car. They want to know the mileage of your car. When asked directly they do not lie saying they are trying to sell you a warranty. I have told them twice to stop calling and have received a total of 3 calls so far.
I got the same things from these guys. The simplest thing to do (if you have an iphone, not sure if droid is the same), is to click the info button next to the number...scroll down and hit block caller. Situation resolved.
