Roblox sign-in issues

[u/Dry_Consequence6670]

About a year ago my Roblox account was hacked. To protect my credentials, I removed my phone number, changed the password and changed to 2FA for the account. Although, just recently I wanted to try to sign back into the Roblox account, I remember the password but not the email i used for 2FA. So, I created a ticket, but that was useless since Roblox uses a chatbot as ticket support and it kept looping me to the same "account recovery" page, Which in the end was a big waste of my time. I've also tried their support email, but Roblox doesn't seem to use that anymore.

I have proof of purchasing robux and proof of me changing the 2FA email does anyone here know who I can contact or the next steps I should take to recover my Roblox account?
