Tried to delete autenticator

authenticator dead, cant log in. i removed the authenticator when it started dying but still it had me add the one on my phone. i just replaced my computer and now its not only asking me for the physical authenticator code, that i removed it is asking me for the digital phone one to that i can’t log into. i need to talk to a gm and the customer support number hangs up on you before it even rings.
