Did you ever get your car rental dispute resolved?

I'm going through the *exact* same ordeal with these same
two companies.

In my case, and it appears yours as well, they have violated
Wisconsin Statute §344.574 (4). Also in my case, through
correspondance, they have violated the Fair Debt Collection
Practices Act, 15 U.S.C.A.§ 1692 et seq. through flasely
stating they are exempt from Wisconsin Statute §344.574.

I appear to be slightly behind you in timeline... so any
info you could pass along would be helpful.
