Vumatel - adding insult to injury

Vumatel installed fibre in my neighbourhood a few months back. Despite numerous complaints they left a mess on my sidewalk. They damaged grass that they did not replace, they replanted dead grass, they damaged my flowerbed edging which they did not replace, They dug out and did not replace one of the shrubs growing in the flowerbed on my sidewalk. Now to add insult to injury they repeatedly harass me telephonically and with door-to-door sales people trying to sell their product. Even if I was interested in switching from ADSL to fibre, which I am not because there is no cost benefit, Vumatel have put me off ever using their services!
