My question involves an injury that occurred in the state of: Illinois

So this is my case
I am working as technician installing internet at houses. In one of my jobs, the wife granted me permission to drill a hole to the floor which was specifically pointed out where the location will be. The husband wasn’t at home but when he returned he was't happy with the location. Because the style of the floor he has is no longer available is require me to replace entire floor. My mistake was not adding notes she gave me permission. I am working for a company contracted with a Comcast and now they want to pay it to the customer entire floor. What my options are to dispute this?!
