I have received calls from this number in the past but didn't answer. Today, I received two calls, I answered the second call. A man asked for me by name and said the call was regarding my 2013 vehicle (he knew the make and model as I believe the Michigan Secretary of State makes this information a public record). He told me my vehicle's warranty was expired. I stopped him at that point, told him he was wrong, my friend owns the GM dealership where I purchased my vehicle. I am up on my warranty. I told him not to bother me again.
