Bad service

I would like to report metro fibre, the fibre installation was done in February 2020 and the fibre box with router was installed round about 18 March 2020 were by we were told that it would be activated two weeks after installation. I have been calling metro fibre every day with no luck and they're laying every day. They said that their is a problem with the connection to my house, which is not the case, a technician was here and he told me that the problem is that metro fibre is not activated yet. But every time i phone them, they say that it is live and activated. Please assist because this is verry unprofessional and i have children that needs to have internet to have access to school work. Please assist. There is no follow-up done by Metro Fiber and the service is really bad.
