Unhappy Metrofibre customer

We are very unhappy with the service we are receiving from Metrofibre. On two separate occasions we have waited (and currently still waiting) for over a month to have our fibre activated. Each time we phone our ISP we get told that the matter will be escalated to metrofibre, to no surprise nothing happens. We only get told that Metrofibre has not released our lines. This has become a massive problem and resulted in a financial strain as we work from home.
