Worst service imaginable from Metrofibre

Metrofibre is the fibre contractors in my area. Metrofibre installed the fibre cable to my house, it was installed less than 15cm below the ground and not in a conduit, 3 weeks ago we were doing work in my garden and the line was pulled up, which could have been avoided had the line been connected properly. Metrofibre sent their subcontractors and I got a ridiculous quote of R5700.00 to do it "properly" this time. According to everyone it was installed to Metrofibre's specs. I have now been fighting for 2 weeks, for someone to assist me in fixing the line, its impossible to get a second quote and emails and phone calls go unanswered.
