Appalling fibre service from Mweb

Fibre was installed this week but internet stability is shocking and my existing email stopped working. I called Technical support and waited 35 minutes to speak to a technician who cut the call before the discussion was finished and without resolving any of my issues. The MWeb voice message offers customers the facility to log a call online but the facility does not exist. There is no email facility to talk to anyone. I am thinking of cancelling before this gets any worse.
