Caution € 30, - not for Austrian accounts

Have to give me the 30 - bought and tried to enter the code in the XBO. Unfortunately, this was not. Then I did it online ... everything ok, 30, - on the account.
After that I wanted to buy something in the store, but each time an error message.
After proper research, I found out that the 30 - code applies only to the German market.
So if I want to use the credit I have to live in DE.

According to the product description of the code is supposed to work for AT & DE ...
Amazon says that it was not their problem, because I see the credit on my XBox Live account.
In my opinion, a mistake in the description ...

So I do not buy anything from Amazon digital more than next might also Russiche Steam code distributed as a German or Austrian. And in the wake do you get a response from Amazon, such as: "You have received the token, that he does not go because we have the wrong product description, is not our problem"
