Class pass will charge you and doesn't email you a receipt or remind you that they charged you after the trial period. When you tell them you want a refund and that you don't intend to continue the membership, they say "ok, we will cancel your membership" and you can't use the credits you paid for. They customer service people (chat room only--you can't call) are sarcastic and unkind. I would stay clear of this company.
