there was damaged cable between box and light pendant so I was really lucky to find the box using my inspection camera and be able to replace a cable without destroying big amount of ceiling. There were just two small holes in the ceiling that has been just renovated two days before.Tell me please, who are these 'most electricians' to whom you refer? I hope you are not suggesting that the vast majority of us are cowboys?
@GMES: yeah, I know. I think I will talk to her on Monday and we will solve an issue. She is arguing to pay 150 as other electrician told her I cant take money for doing that. But she still needs to pay the rest of price:/ Anyway, I believe we will figure it out and she will pay at least price close to the one agreed at the start.
