Terms of service found here:

14. VIP Membership
"The functions and features given to VIP members are subject to change at any time. This may include the removal or addition of features. It is in our sole discretion. The functions and features listed are at the time of purchase. Updates happen from time to time and those features may be subject to change. In the vast majority of cases, only additional features are added for the benefit of the VIP member."
It goes on to say refunds will not happen due to "buyers remorse" etc and also says the site can change the Terms of Service at their sole discretion.
The silver lining is that same sole discretion is with TheChatmaster so if you want to convince him otherwise- feel free to PM him here:
