This is a personal problem which I don't know where to put this so I'll say it here.

I have owned minecraft java since Jan 30th and my account has come with a free windows 10 code however on a different device I have claimed this to see what would happen.
After clicking on the redeem the code disappeared before the code was typed I then closed out the browser and shortly after on my other computer I reset it.

I have no way to claim windows 10 now and I have no money to just buy it please help.
