Very Unhappy client

where do I begin, I app**** for fibre it got installed and set up. I paid and everything was fine. My internet cut out randomly I went two weeks back and forth with vodacom agents to get answers finally two weeks later an octotel agent came out and checked the line and found out my fibre line was damaged to which he said it would have to be reinstalled, to my surprise reinstalling would cost R1700 which isn't the issue. The issue is the way the fibre line was installed it was such a sloppy job first thing is the line was run on the floor and in a walk way so for it to be damaged, the glue came loose, it was just really sloppy now I have to pay a huge amount of money for damages that isn't even my fault. heres the kicker to cancel I will have to pay R2500. If any one can assist me please I would be grateful.
