Been there, done that. If it has been deleted, no matter how much you grovel and moan, Orange will not bring it back! The "techs" say once deleted and purged, there is no way they can do anything.
So, cross everything ... but be prepared to lose it all (I lost everything since my Freeserve days).
Otherwise, email/phone your games account folk etc, explain what's happened, and I would expect them to be helpful.
