They also sent my withdrawals with an obscenely low miners fee, and after 3 days of waiting for a confirmation, I paid a huge acceleration fee to a mining group to get it confirm
I understand that after 25+ confirmation you should have the money there by that point and even 1 confirmation is usually enough but that sounds like not something quite common but due to some software problem, since they managed to help you out I would say that is a good customer support if you want to look at it that way as well.
Only thing I am not certain about is the not being able to bet, I have been betting here for a while now and not really faced any problems at all, never got my bet even voided, so I can't talk about that part.
