LA Fitness told me twice that they would cancel my membership but continued to charge me. They charged the main holder of the account for an entire year after I tried canceling. When I called them to confront them about this they kept passing the phone over to someone else. Nobody I talked to cared about the situation. They kept telling me that I had to go in person to a gym and cancel my membership.
If you don't pay your membership the billing department will harass you on the phone at least 3 times a day, EVERYDAY. They'll call your emergency contacts. They'll even google where you live and contact your landlord. However, when you try to settle a dispute with them, they are nowhere to be found.
