Said I was referred to them by a friend for a free CT heart scan that is not covered by insurance (I don't know how he knows what my insurance covers.) He doesn't give a company name, but gives his name as Christopher Koobah (?). Sounded like a robo-call. Caller id said it was from Park Forest, IL.
