Dec. 13, 2024 - Tech switched user to new email and new password - no access now

I tried to login to update one of my accounts.  I currently have three accounts from the beginning of Homestead almost 20 years.  Login gave me a window and only option was to call in to solve.  Called number and tech told me I needed three separate emails, one for each account. So she updated all three accounts.  One account is working the other two do not allow me to access websites for updating.  I get a "404 - File or directory not found".  It has been almost a week after speaking to additional techs without luck.  Does not look good and I am currently using website for registrations and such but it needs to be update.  Any advice from anyone would be helpful.

Thanks,

Eric
