As an owner of multiple weeks for 21 years, we have not ever received a check from them. There have been many years where we did not use our weeks. With the no pay unless you go, they have the option to use your "unused" weeks because you did not pay. If you pay, you go or exchange or rent to someone yourself.
As T-Dot-Traveller said, if you have it in writing, it would happen. This would be a separate Addendum, not in the generic multiple page contract that you initial. You would have this signed by yourself and the VLO. I would be surprised if you had one.
