Couldn't verify, can't login

Hello,

Its my first time signing up on Zoho, and I put in my domain and my boss's number. I did not realize it was going to verify, so I returned to previous page to put in my personal number but now it says the domain is attached to another account, but I can't get into it.

Could you please reset or remove domain "drdental-eg.com" so that I can set it up from beginning? Thank you.
