Disgusted Subscriber

Good day, I need some assistance, I have tried on numerous occasions to contact and email the Flexi club and Club Leisure offices with regards to a subscription **** we were caught in. We were pitched this marvellous great deal and obviously push coming to shove we realised that we signed up for something totally different as to what we were pitched. I have tried time and time again to cancel this subscription and have had no luck, they did send a email once to say that I was not able to be reached yet none of my contact information has changed. WHAT TO DO? I hope someone is able to help!!!!
