Flexi Holiday Club Reservation Hoax

It seems Flexi Club take no responsibility to ensure the reservation you made through clubleisure is valued. On our arrival at Natal Spa Holiday Resort I was informed by reception that Flexi Club made a double booking and they offered us a smaller accommodation. I had to call the rest of my guests to inform them the unit we got was only a 2 bedroom and had to apologize to them for the inconvenience. The resort told me I had to take the issue up with flexi club, which I did. The response I got from flexi club the next week was that the resort told them that I voluntarily accepted a smaller unit because of a problem with \ in the 3 bedroom unit. That was absolutely false as I could not even have seen the unit beforehand - the resort immediately, on my arrival, told me it was a double booking and it was Flexi Club's problem. Another week has now passed, but I did not receive any apologies or explanation. The problem I have, as many other Flexi Club owners, is that I cannot cancel my contract with them without losing everything?"
