VOX App - Password reset unusable useless piece of functionality

I am highly ****ed off. I changed my damn password on the Vox application. Every since I changed the password, my Fibre is no longer working. I called in to the contact center of which I was advised that if I change my password on the application, it resets my entire system and a technician has to come out to set up my fibre.

If this functionality messes up your clients entire connection, please can you explain why the hell you make this stupid useless capability available to your end user! It is the Easter Weekend and now I am sitting without internet.

I have been advised that you are not sure as to when a technician can come out. I would like this matter resolved please as now I am being held liable for the poor implementation of poor, untested pieces of system functionality that has been deployed to a production environment!
