Do you have a Better Business Bureau in the area where you can lodge a complaint?
How about the Good Sam Action Line
"Action Line Consumer Advocacy
If members have a dispute about an RV-related issue, they can count on the Good Sam Club Action Line to help. Action Line cuts through red tape, gets answers, and works to resolve problems on members' behalf.
If you prefer, you can also contact Action Line by sending an email to actionline@goodsamclub.com or by writing to Good Sam Action Line, P.O. Box 90020, Bowling Green, Kentucky 42102-9020. Please include a brief letter of explanation and if applicable, copies of receipts or other pertinent records."
