Bad service

I joined the gym on promises given by a pushy sales representative, only to be at a gym with bad customer service and when I asked to cancel my contract after being told they would help me with a change over of ownership, to be treated rudely, told its my problem either pay cancellation fee or carry on and then told to come back in the new year as he wasn't able to help me then, I then go back in the new year to be ignored for 45 minutes after which I left without being helped. Now all I want is to get out of my contract from the rude staff
