Cannot access my zoho domain email no matter what i do..............ZOHO cannot find the domain/apps. account either.........

Hello, I'm trying to run a business here and really in a crunch. I have a few email issues here - some confidential. Would a ZOHO moderator/manager here/elsewhere please send me a private message somehow for further consult? Please advise. Thank you all very much.
