how can i terminate a timeshare

Can I finish the contract?Its for 14 years.I have already 6 years

I have owned a deeded timeshare at celebration world resort (which is now festiva) for about 20 years. For the first say 15 years I was told I had week 52, which meant I counted to the 52nd Friday of the year and that is when my week started. Now , starting last year when I called to exchange my week into rci, festiva tells me that I have points assigned to me and they tell me what weeks are available to me to exchange with rci. My deed states that my week is in “The plan” . I am trying to find out what the plan is within my deeded timeshare originally thru celebration world resort. I believe festiva is trying to get everyone into their points system even though we have a deeded week.

I have started the process in selling my time share, but the funds have been seized by Mexican government, with very scary emails from the first email I received from them .
