Minecraft windows 10 code claim

So i have a littel bit of an problem i trayed to claim a free copy of Minecraft windows 10 Bedrock edition for the last 2 weeks but Every time i click on the button Claim your free copy it says

[*Error!* It looks like we've temporarily run out of gift codes for Minecraft for Windows 10. Don't worry though, more codes should be on their way. Please check back later!]

at first i thought i didnt had Minecraft for so long that i get the free copy of it but i have the game since 14.02.2012.

Then i trayed contact Mojang with my problem through an E-mail but i never gotten an email back.
