Caller ID says UNKNOWN NAME. No voicemail left.

Caller ID says MICHIGAN CALL. Caller left message, claimed to be from a law office. Called number back (dialed *67 first) Female answered with "Law Office, may I help you" called back later and got a voicemail greeting, no mention of law office, woman sounded illiterate.

This woman calls me about debt consolidation. When I instruct her to remove my name and number from my list, she just hangs up. So I call the number back. She answers it, again with some reference to a law office, and addresses me BY MY FIRST NAME. Very rude, in violating of FTC Do Not Call list. I will be doing a reverse number lookup and filing a legal complaint.
