I can't login to gitlab.com

Hi, I’ve been a long time user of gitlab.com but I haven’t logged in for a long time. Now I try to login using my username and password, and it tells me that it will send a confirmation email that never arrives, if I try to access with my google account, it takes me to a 442 error page that says: “Sign-in using Google auth failed Sign-in failed because Email has already been taken.”, and if i try to login using github it says it sent a confirmation email which never arrives. If I try to recover my password the email never arrives.

Is there a way to solve this?

Thank you very much for your time .
