I don't have an authenticator and I am locked out now

so I have been trying to pre-purchase Shadowlands. Every time I try it won’t accept my password, yet the same password logs me in every day to play. I try to get help but Blizzard obviously doesn’t want to keep someone who has played since the second month. It is a damn merry go round over and over and I have had enough.

I have tried to reset my password but it requires an authenticator but I DON"T HAVE ONE !!! it has been out of the loop for years. I need help, but there is no phone number, no email address and now I can’t log in to the damn game!!

I have had enough.
