Totally dissatisfied with iExchange

I have a week's Timeshare at Fairways in the Berg. It was suggested that I join iExchange and instead of one week at the same venue, get four midweek stays at different venues. It sounded wonderful and I contacted Iexchange to find out about their offers. I was told that I could choose from umpteeen resorts both local and overseas. The booking fee was nominal. I just had to agree to transferring my week to iExchange and experience this wonderful offer.

I was told that if I agreed to transfer my week, I would be 'tied' in for 3 years - but hey, with such sales talk who wouldn't? What I found is:

Their website is not user friendly Their fees (only given after I joined) are not minimal Whatever resort I tried to book, I was told was not available and to keep trying They will not reverse my week back to me although their is no legal contract between us.

So this means, for the next three years I cannot even go to my own timeshare without having to pay a whopping fee. I am now considering going the legal route which is my only recourse. Their advertising gives the complete incorrect picture of what you can actually get as everything is 'not available - try again'. They do have staff that are sympathetic, but it is impossible to get in contact with anybody in Management
