I've gotten similar calls. This is who they are:
Stillman Law Office
7091 West Bloomfield, MI 48322
248-851-6000 Phone
248-851-6029 FAX
[email protected] email
Main focus: Commercial and retail debt collection and litigation.
I've thought of calling the business department in West Bloomfield's City Hall and complaining directly to them. Reason being is they need to get a license to work in the city. Don't know if this will work but I'm seriously considering it.
