Unaffordable levies

I am a concerned QVC holiday club member who joined the club about 8 years back. In the beginning the club run smoothly and the levies were affordable. I was still healthy with a regular income. In the past few years I developed a lot of health complications like heart , diabetes, high blood and two mayor back operations that changed my whole financial planning for the future. I will not receive pension from the government because of my 7 years service when I go on pension. I did not foreseen all these things happening to me. I simply won't be able to afford the levies monthly because of all the money needed for paying medical bills. I have contacted them and try to be reasonable but were threatened with legal action.<br> The last few years their service were poor because did not have enough points to get VIP treatment. You always end up with s****s that no one want to go to. The same places over and over again. About three years back when me and my family went to one of their resorts they approach us with specials. My son paid a deposit of R5 000 just to find out that they were ******* and ran away with the money. Since then I tried to get out of the contract with no joy. What to do?
