Call on my cellphone. Did not leave a message. I only give my cellphone number to friends. My best guess after looking up the caller from Flint Michigan, this was a robo call like others trying to give me a security system on my home.

It's a scam for a security system. There are prompts to be put on do not call list, but I don't understand how they got my number either.

called and did not leave a message.
