I had Minecraft on my account a long time ago and out of nowhere my game was deleted and I'm asking to buy it again even though it was already purchased and they deleted it from my account

This seems to duplicate WEB-7179 

Please note that the game hasn't been deleted, there is an outage currently going on which affects the xbox servers and in turn, the Minecraft licensing/auth servers. This means it's possible you may be unable to change your name, your skin, or be able to play Minecraft at all, regardless of your launcher. Your purchase is not at risk however and if the game shows as unowned, this should be resolved when the outage is resolved.  According to @unknown
