Collection agency scams?
Interesting enough, his office manager's husband received a similar notice not long ago.
Two years ago, a got a letter from a collection agency claiming to have been hired by BMG asking me to pay a $30 debt. I hadn't been a part of BMG for over 10 years. When I asked the collection agency to provide a statement as to what I owed money for, they could not, and I never heard from them again.
