Don't "upgrade" your timeshare with Flexi Club without legal representation

Is there any legal process that can be entered into with your timeshare company if you have been "bul****" into cancelling your paid up timeshare and ended up with a newly bonded timeshare? Our paid up timeshare is just gone. We asked how we can cancel the exiting timeshare and was told that we have to pay off the bond. I will never again take out any timeshare with Flexi Club without having the documents reviewed by a lawyer.
