Disappointed Pensioner Attempting to Cancel Membership

Shortly after I retired I received a phone call that I had won a prize but needed to attend a presentation. I duly attended, where I found a room full of pensioners who were all lured there with this ‘prize’. I realise that I acted hastily in signing up for this ‘holiday reservation scheme’, since it turned out to be no more than that, such as Lekker Slaap & others, except you do not pay an annual fee to those apps. I have asked to cancel but was told I cannot cancel, but I can try to sell my membership myself, which off course would be impossible. I have now received a schedule from them showing annual fees until 2064, which would mean I would be 115 years old, if I’m still alive. Based on this schedule, they are offering for me to pay R50,000 settlement, then they will cancel. I’m a 76 year old pensioner & cannot afford to pay R50,000. I’m prepared to pay the outstanding amount & then cancel the contract. Due to cost of living, I’ve had to move in with my children, so I cannot afford these fees & least of all the expensive holidays they have on offer. Please be very careful of schemes like these during an emotional time like retiring.
