I wish to know how I can prevent my granddaughter from purchasing robux from the Roblox games. When she clicks on the button on a game to get an item for the game there are only two options one is view the other is buy. When she clicks buy it shows details of payment methods which are beloning to me. She doesn't have a bank account and is playing this game on her own website with parental controls on it, but this does seem to prevent her from purchasing robux. I wish to stop this happening further, could anyone enlighten me please.
