Incorrect information provided for me to join

I joined flexi club last on the 10th of March, a paid a deposit of R1800 and i was told that i can start making reservations after the first payment and i can start using my points. I have not received any membership number or welcome pack, i called today to check when i can start making reservations, i was told i can start now but i will have to pay for all my reservations as i can only start using my points after 12 payments... then what is the point of having this thing and what exactly am i paying for and why was i **** to when i joined... This was not explained to me. and i want to cancel and i want my money back
