Bad service

Metrofibre installed our fibre network when it was available on our street. The service was not bad to begin with but not what you would expect from a fibre connection. A few months in the service we got was terrible the connection kept dropping so much so that we were unable to do work from home as was expected of us. Every time we would call they would say they are escalating the issue but it never gets resolved it might get better for a few or so and then we are back to square one.
