Cancellation of a membership

a presentation was done by the touch down group, whoever everything was explained to us expect the yearly fee, it was only mention. although we signed the contract that stated that we fully understand. the contract was signed under false interpretation.<br> <br> a letter was sent for cancellation but no response was received from the group.<br> <br> i would like them to pay my money back, as i don't want this membership any more, because the yearly fee, is exactly the same amount as my accommodation.<br> <br> Please help.
