New phone number, cant log into account

I haven’t played for about a year, and in the meantime, I got a new phone & phone number. I am now unable to log into my blizzard account because it has an authenticator attached to it, and cannot verify my identity with a text message. I cannot even submit a help ticket because I can’t log in into my account. I had to make a new account just to ask for help here.

Does anyone have any ideas about how I can recover my account?

same here, and we cant talk with anyone there btw.
I didnt manage to create a ticket or contact support (maybe we can not)
