Re: Timeshare company NOT honoring cancellation policy (by Lance C.):
You said it was sent certified. That usually means you have a receipt as proof of mailing. Do you have that receipt?
Also remember that the developer has up to 45 days to refund your money. I would cancel or put a hold on the credit card with which you made your down payment. You can also file a dispute with your credit card company.
