bad installation and no liability metro fibre

I am not happy with the service i have with Metro Fibre. I have asked this supplier to fix the poor installation done from the road to my home. this is now 2 weeks later and there was 3 times people there and just left and said it is the maintenance gents work to fix this. I have spoken to Metro Fibre more than once and they are not helpful at all. they tell me it is my supplier that should fix this where I have a contract with but I do not agree and told them that they cannot be held liable since Metro fibre installed the line and only 2 months after the complete installation I signed a contract with webafrica so how must they be liable for the poor installation of metro fibre?? i have pictures of the poor installation but no one comes to fix this and put it on the ground where it should. this is a 35 to 40m driveway. this is not good service from metro fibre at all and the lady I spoke to last week said they are partially liable for this but they are fully liable for this. all my cables are pulling out of the condo pipes and makes loops the full 40m down to do the heat. I do not have words anymore and they even said I had to open up the ground and they will put the pipes into the ground, yet I did it an now no one wants to fix the pipes and put it in the ground. I have a lot of pictures
