still not sorted

My issue with my contract through holiday club has still not been sorted out. the contract should of been cancelled in the cooling off period and a year later i am still paying. i have sent e mails asking what is happening , the only response i get is a phone call a few weeks ago saying they dealing with it. firstly i have asked to be contacted via e mail as i cannot always answer my phone and secondly nothing seems to be happening and yet every month im billed. I called to cancel my contract due to financial reasons and yet every month i have to use a overdraft to pay it as nothing is happening. they requested my membership number which was sent on the 1st october, then i e mailed them on the 4 oct,19oct and 17th nov asking what is happening.
