Although not software, gym memberships are notorious for using all manner of slimy tactics to keep you paying. Online reps can't do anything, your local gym somehow never has a "manager" around who can do anything. You can "freeze" your account but then they can just arbitrarily unfreeze and start charging you again. Very close to having my CC company issue a charge-back to our local gym for fraud. Very shady and hopefully these can be made illegal.
