Flexi Club worst investment ever

I can no longer affort my flexi club point as they are worth basicaly nothing, its costing me more than R7000-00 a year but I cant go on holliday every year. I contacted Flexi club to request to sell my point and first they wanted me to buy more point for more than R15 000-00 which I cant affort and then I can cancel my membership after 7 years, which would not work for me. Then they refered .e to Cape Escape to sell my point. I paid R11-00 per point in 2002 as an invetment and now after 18 years the tell me the resale value of my points are between 80c and R1-50 per point. How is this possible. I also apparently can't cancel my membership . Is there any other option to get rid of the worst investment of my life. I would not recomment flexi club to anyone as joining them is most probably a decision you would regret for the rest of your life. Worst company ever.
