Sometimes the company which you charge you silk through chargebacks when they think it's an illegal transaction (so that someone else broke into your account and charged it). You'll have to call that company and tell them to contact JM about it telling it was a mistake, then you pay JM again and if it goes allright you should be able to play on

hehe
Note: I don't have any experience, this is just what I get from SRF about it.
