MetroFibre- Shoddy Work, Poor Installation at Ifafa Beach

Metrofibre installed cable to our property at Ifafa Beach, without letting us know they were going to be on our premises. It was terribly done and is a shocking piece of work, across the verandah and over the path which is both untidy and a tripping hazard. It was signed off by an unknown person and they have the document but no idea as to who it actually was. I asked them to come and check it out which they did after a few months and the tech guy was shocked at the shoddy installation. They are unwilling to re-install it properly so we have asked for it to be removed. There is little or zero communication from this company. I would really like to know how they accessed our property.
