I had an incident last year where my fibre cable got damaged soon after the installation, Zoom fibre came and did the diagnostic and they said the fault was outside the premises and was caused by the people who were building the wall . I disputed that and they came again this time with the machine to check where the line breaks and the fault on the cable was somewhere else , they went to charge me for this and I told them how unhappy I was because the installation that was done was very poor and the cables outside the yard were not covered (no hole was dug), now I had an incident over the weekend when the municipality came to cut the grass outside and the cable that’s not underground was damaged , now I am told I need to pay for a reinstallation for something that could have been avoided had they done the installation correctly . I am not happy with their service since I started working with them , I wish there was another company in the area , unfortunately it’s only them , it’s unfair they should be fixing this with no charges
