Hi, you may want to entirely ensure that you're typing in the password correctly, including making sure caps lock is off, etc.

If nothing appears to be working, the most you can do is maybe present the billing information or redemption card code for which you bought the Robux as verification, sent to https://www.roblox.com/support - this is the only last method, if you've not an email.

If nothing comes up after that, your account is likely not retrievable. On a new account consider adding an email so that you can get into your account. Accounts without emails are at highest risk of being hijacked as there's little that can be done to get it back.

''Please note that I'm a player just like you. I'm not part of Roblox staff nor do I have contact to Roblox staff, so this is just advisory. You must use Roblox's support page if you need to contact Roblox.''
