I cannot verify user or phone for domain altairdental.com

Hello, 
I was creating a new referred zoho account for the domain altairdental.com. The SMS came like an hour after so when I entered the SMS code it did not work. 

When I try to login the phone number I get this :

Oops, it seems you have not verified your primary mobile number yet. You need to have a verified
primary mobile or email to reset your password.

And if I try to start the process again it says there is already an account associated to the number **** **85

How can I verify the mobile number?????
