Cannot access mailbox. Domain switched to Soho instead of Zoho!

Cannot access mailbox. Domain switched to Soho instead of Zoho!

I was under my account > Profile > Email Address when I saw an option to add email. I clicked Add Email and it asked for an email and existing password. I thought it was asking to verify my existing account so I entered my existing email and password. However my phone auto corrected Zoho into Soho. Now I cannot access my account because it changed my primary account to @Soho.com and it wants me to verify that email address! Please help!
