Classpass make it very easy to sign up, yet the cancellation process is hidden away. You have to confirm three days before your cycle expires, and even then you have to troll the site to find the link. Following this, you have to speak to a customer service rep on chat to explain why you want to cancel, while being offered 'lite' packages.
Downright scam. Their main income stream would be from members who forget to cancel or just can't be bothered given they make it so difficult.
