Windows 10 Edition code cannot be redeemed

Cant get the minecraft windows 10 edition code.
I can not get the code, although I got minecraft 2016 and therefore the code should be mine.There are also many people with the same problem.

The problem has existed for a month and there are also many people like me with the same problem. I have already written to minecraft support, but you won't get an answer there, even after a long time, which is why this is my last hope to get a reasonable answer
