24 Hour Fitness review: membership

I took out a membership at the Westhiemer branch in Houston, TX. When I took it out I had asked if this would permit me to use the Woodlands branch on Lake Woodlands. The assistant told me YES it would be ok and that I wouldn't be able to use the one in the Galleria area. I took out the membership based on this information. When I went to the Woodlands club I was told I had to have a super-sport membership. This required upgrading and paying over more money and increasing my monthly payment. I was missold the membership based on false claims. They will not cancel my membership without an exorbitant early termination fee of $300. If I stop paying they threatened to send it out to a collection agency. Their customer service is very poor. I have complained to them and basically they want their money. A terrible company
