If you would like to see what you've bought hit the "3 bars" in the top left of you screen if you have that open already hit "Trade" then "My Transactions"
Hello legoatatdriver.
Very weird this happened! May it be something you did to lose those 640 ROBUX? If not, i would recommend you to click on the TRADE icon. Then go over to MY TRANSACTIONS and take a screen shot of your transaction list! Send it to ROBLOX: [email protected]
And wait for their answer!
PS: ROBLOX may ask you for more information. But, if this is true. You shouldn't have any problems cooperating with them!
Good Luck!
