My original post about this:
I have purchased the Mists of Pandaria CE. And have attached the CE code to myBattle.Net account. All worked fine. But . . .
When I logged into Diablo 3 and SC2 I did not have the Diablo 3 and SC2 Pandaria related sigils, feat of strength achievements and SC2 avatars awarded to me. Is there anything that can be done about this.
I know Blizzard's policy about achievements is if not working try again. But I can't try this again. I can't add another Pandaria key to my Battle.Net account. And I shouldn't have to pay for the Pandaria CE again to get this.
So is there anything that can be done about this?
The Diablo 3 Panda related achievement (has attached sigil and accent I have also not received)
The Starcraft 2 Panda related achievement (has attached portraits and decals I have also not received).
The Blizzard blue there told me to contact customer support so I did and put a customer ticket in. And the response I got was this:
Log in to World of Warcraft and see if that works. It did not.
So I replied and got another response to the same ticket:

I have not still received the Pandaria CE related achievements inside Diablo 3 and Starcraft 2 yet. Hence I am writing a bug report here about this. Because I was told to by the customer service team.
Normally I would just re-attempt the achievement. But I can not re-add CE game keys to accounts to get the achievements working in SC2 and D3.
 It seems the Pandaria related achievements have poped up in Starcraft 2 now. But not in Diablo 3. So still bugged in Diablo 3. And am waiting to have the Panda achievement/sigil/etc in Diablo 3.
