BritelinkMCT service is the worst

I cannot believe how difficult it is to get these guys to do anything. We have been requesting a fibre service for a new multi-tenant business park for months and no-one responds. Impossible to call anyone - the switchboard asks for us to leave a voicemail message! Is that how switchboards operate these days? And no mobile Nos on emails from the staff who have communicated with us, so no way to contact them! Frustrated beyond measure. I would like to find an alternative service provider.
