Before you cancel Best Of Gym, check these
- Read the notice window in your agreement. A letter that arrives after the cut-off can miss that month's charge.
- Annual fees and monthly dues are sometimes billed separately. Ask for both to be ended.
- A home club can have its own rules. Name the club in the letter so the request is not bounced between locations.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.
