Received a call on my cellphone from this number. My number is a UK number. Came to this website to see if I could find out who called me as I don't know anyone in Michigan area.  Have been receiving a lot of unknown callers on my landline too. I never answer nor ring back unknown numbers unless they leave a message. Thanks for all the info - its really helped to clarify that it might be a scam caller ... though speaking to someone in the UK might make the scam artists more out of pocket the more they keep ringing me.
