Online Code only for Germany !!

I am from Austria and wanted to invite 30 of my MS account but the code has not been credited.
By support from Microsoft it took about 2weeks until the amount has landed on my AT account.

Through the Microsoft Support I have now learned that there are only 10, 25 and 50 credits in Austria.
which also refers to the codes that are offered here on Amazon.

For the service of Amazon, I give clear 5 star because I get the same code since.
but only one star that nothing stands in a headline or product description that this code is only for Germany.

So once again for Austrians: 10 + 25+ 50 credits codes for Austria all others are German Codes
