Unhappy customer

I had Frogfoot install an internet cable four years ago. Had plumbing problems ever since and found that Frogfoot had broken a plumbing pipe during the installation. A piece of plastic had been put over the hole. A root then grew into the hole which blocked my plumbing pipes. They will not reimburse anything for the plumbing problems they say I signed the consent form obviously I did not go and dig up the whole area to check it was done properly. I signed off because it looked ok from what was visible. I am very disappointed in their decision to not reimburse for huge plumbing bills. I would not recommend them for installations.
