Brave's changing of bat system

Brave changed their system and the choices I have will not allow me to sign in. Obviously, they changed what wallet can be associated with brave. I only used this with brave and when they changed it, I lost that account. How can I contact them to find out what account was tied to brave so I can either reattach it or move it to the one they want to use?
