A failed SIK refers to a situation when you chose to install your service intead of having a technician come out and the service would not work. Then we scheduled a technician who came out and determined that the reason the service wasn't working was due to how it was hooked up inside the house.
If it was an issue with the outside lines, or the equipment you would not have been charged, the charge in this case is for the technician to come out and complete the installation.
