I bought 800 robux but didnt get it.

Punish your boy and tell him to NEVER make purchases again without allowance.. And I doubt you can get the money back because your son would've payed for the ROBLOX virtual currency known as robux and he as probably bought clothing and game passes with these
robux so nor Microsoft or the ROBLOX team will be able to get the robux back because they are unable to take the bought items off his ROBLOX account. Also change the settings on your Xbox to make it require a passkey or your password when making a purchase!

I can’t convert it into robux because it doesn’t show the roblox robux in the redeem section so i can’t get robux

Rewards redemptions change from time to time so some options disappear but may come back later. I looked at my redemption area and only the 800 Robux one is there.

I know from previous threads on here that Robux options come and go...some options disappear for months before reappearing

If you bought on the xbox you will need 800 microsoft points to buy it.

If you get it at the story the game has to be new or lucky if the person didnt use the code,

otherwise it should be in the case.
