I tried registering and business mail account for my domain http://www.tandentalsurgery.com and filled up everything then it ask me for the phone verification code but it only came after a few hours. 

When i finally got the code and fill it in it then gave me a server error and redirected me to the registration page so i had to re fill in all the details again but now i can't even submit because it says the domain is already registered to the mobile number xxxxxxxxxx which is my number. 

So i tried to login with the admin account i've filled in during the first time and it says no such account exist so now i'm stuck, 

I can't register my domain, verify my phone number or even login what do i do?
