Well i contact them.
Mojang Support team told me to contact Microsoft support team as they are not in power to do any promotions on xBox???
Answer was:
"The editions of Minecraft available on Xbox are supported by Xbox Support. They can help with things such as game installation, adding downloaded content, billing, network issues, and console troubleshooting. You can view country-specific
ways to contact Xbox by visiting support.xbox.com/contact-us."
So who is in power to dealing with this as Microsoft team sweep responsibility to Mojang team and vice versa??
Also they told:
"If you have purchased the disc version of Minecraft: Xbox One Edition, provided you have fulfilled the necessary criteria then you can still claim a free copy of Minecraft for Xbox".
Is there is any glitch that I can not download it??
