Metrofibre a no-show

The main fibre line to my home is damaged, causing daily drops in internet connection. This has been reported almost daily since October. They keep on sending a technician to check everything but the main line, even though support confirmed that the main line is faulty. It has been two weeks since the last technician has been here, numerous calls, being off-line daily, and no joy. I have now resorted to cancelling my line, and will find an alternative supplier as nothing can get escalated, no manager even attempts to return your call, support can’t get you in contact with a manager and it’s the most frustrating thing when they completely disregard you as a client.
