Do NOT trust ClassPass. Their business model: scam new subscribers until they notice and quit.

Of course they don't provide a customer service phone number -- there would be too many valid claims and concerns. Here is my experience

1) I signed up for the 2 week free trial
2) Before the free trial expires, I try to set my membership to "ClassPass LITE" for $19/month but the website is conveniently down and I am forced to contact customer service.
3) Customer service (Gaelyn C.) personally confirms that my membership is set to $19/month beginning this cycle.
4) Despite the written confirmation I am charged $45.
5) I contact customer service only to be told that there is nothing to be done.

Despite my two friends who BOTH got charged $200 "accidentally" shortly after signing up following their free trials, I stupidly trusted the service. This has truly been a frustrating and horrible experience.

Do yourself a favor and stay away from this scheme.
