My husband had a membership at Ballys, then moved from one state to another state. In the new state, there were 2 Bally locations in town, and they both sucked. He actually managed to prove that the services and equipment provided were so different in the new state/town that it was basically a breach of contract, and they let him out. It was a hassle, but he had several conversations with their main office, and he is VERY persistent. They tried to tell him that the manager of the location in the new town would have to document that his gym was inferior, and my husband was like, "That's bullshit! What makes you think this guy is going to document that his gym is inferior to the gym in the other state that I bought my membership at, which he has never even been to?" They eventually saw the logic in that, and just had my husband send a written complaint - then they let him out of the contract.
Good luck!
