Problem in continuing business email setup

Problem in continuing business email setup

Hi, on the 18/11 I started creating a businness email account for the domain vengenharia.com.br.

However, by reporting the SMS verification code, the site reported an error and instructed it to try again later.

However, now when you try to restart the process it reports the following error message:
"This domain is already associated with this account" ***** 00. "Sign in"

How can we solve this problem?
