I received that email today as well.
My England vs Slovenia CAT2 tickets show as sold.
FIFA just released 150,000 tickets back into the pool. I'm guessing these have to sell before ours sell....
2 x CAT 2 Match 29 (Brazil v Côte d Ivoire) sold I have the following remaining to be sold: 2 x CAT 2 Match 37 (Slovenia v England)
