For post-paid accounts, new customers are suppose to get an email to validate their self serve registration account. They are no longer suppose to register on the Self Serve page on their own.
If this is the process, please remove the Registration page to prevent issues like these here
In place of the registration page, have the instructions here about what a customer needs to do to register for self serve. Also give instructions for the situation where they do not receive or do not see their validation email from Koodo.
