I bought a timeshare in Malta which had a 25 year ‘contract’ which was fine. But in Jan 2012, I was offered free holiday in Tenerife, only condition being that I would attend a presentation I was not allowed to take my friend in with me and the culmination was that I ended up paying £3400 to exchange to a point system. I later discovered that this contract was in perpetuity, and I have never used it during the last 9 years due to severe mental health issues . My son has used it once . We are paying out money for something we don’t use. What can I do?

I purchased a 6 berth apartment for 6 years have only used 3 years. They cancelled in lockdown 2020 and I had to cancel through covid 2021.
They say I have to take these weeks before 2024 but are only offering me a 4 berth in November.
I bought a 6 berth because of my grandchildren so a 4 berth would not be big enough. The week I have is in June so would not want November when it is cold and nothing in the area is open.
If they can’t provide me with 6 berth in summer time can I ask for part of my money back and the maintenance fee I have had to pay
