Windows 10: code redemption

I decided to finally redeem my windows 10 edition for minecraft. I redeemed the code but the game hasn't downloaded. I can't redeem the code again, it says its already been used but I can't actually use the game

Minecraft redemption code

Just recently I found out I could get Minecraft Windows 10 Edition for free (since I already have the PC version), I went on to Mojang, got my code, clicked on [Redeem], took me to Microsoft website, logged in and this message showed up (Shown below). The
thing is, I did wait, a long time. Reloaded the page, re-done all my steps etc, then I decided to go on to the Windows Store, I found Minecraft Windows 10 Edition, went to buy it, selected the code payment option and pasted my code in (from the Mojang website).
New message came up in red reading "Pick another way to pay. This code isn't from a gift card".

My question is, why isn't Microsoft registering the redemption code and how come I can't redeem it over the store even though the code was from the official Mojang website? Any help would be greatly appreciated, Thankyou.

Try that again
Something happened on our end. Waiting a bit might help.
