I apologies for my English is bad.

I cannot post on Diablo 3 Blizzard forum even I have already redeem Diablo 3 code from my copy.

maybe it is because of my WoW account that frozen long time ago ?

I already ask blizzard here https://us.battle.net/support/en/ticket/thread/26907350 but he said that he doesn't have time to fix my problem.
