Umm... one question, have you file the complaint to any of the arbitrator?

By the way, ThePogg has been rebranded to casinoreviews, and I honestly don't know whether the rebranding affect their mediation method or not, but past history told me that they're less transparent than other mediator. Not in a sense that they're worse or better than other mediator, I don't have enough reference to compare their efficiency to other arbitrators, simply just less transparent. Unless I remember things wrongly, they didn't provide a thread-like page that's open for public to read.
