When did Flexi Club changed from a point system to a discount on accomodation club?

I have been a member for years. When I used "my points" this year I was told that I had+-90,000 points. My usage would be +-35,000 points. But when my booking was confirmed I got an account where my levy was shown, minus amounts for the bookings I made. Although I have so many points still available, I will have to pay an additional amount if I want to make more bookings this year. I phoned to clarify this and then later lodged a complaint, requesting assistance, on the Flexi club website. I received no response yet. I gather that the points system is redundant, but what about all the points I have not used previously? What changed and when did the system change? My levy per year is +-R15,000 per year and the amount deducted from my account is about 80% of the normal rate at the timeshare I booked. Does that mean that my timeshare has now changed and I will be able to save 20% on accommodation when I use Flexi club? I am shocked and disappointed as I really do not understand how and when these changes occurred as well as the fact that I am not getting any response from Flexi club.
