I got the same five mins ago i called to speak to Chuck Baker who tried to disguise his voice and put me on hold. Call your attorney generals office submit the info and get a case number to sue for harassment.
I just got the same call about 5 minutes ago as well. Stated his name was Chuck Baker from PTI Services. He was speaking really fast so I it was hard understanding what he was saying. I tried to google PTI services but the only thing I came up with was a transportation company, a university, and a software engineering company in Washington DC. He didn't mention my name or anything, definitely sounds like a scam to me.
