Can't Find My Account [Edited]

This has been my email account for at least 20 years . I cannot imagine that this company cannot find my account .In addition l put in my password and it gets rejected so in create a new one and I’m able to get into my email account after being able to get my emails and get it several additional attempts ND AT ONE POINT IT DON’t accept my password again I change it again accepted and again after serval time I go the same . Now it says Can’t find my account, this is frustrating annoying and disgusting.
