Best Furnace Serviced in Denver CO

I'm a designer and hired SJO to install a multi-pendant light in a stairwell. I emailed a picture of the pattern for pendants with dimensions of the height and said if there were any questions I was happy to clarify. They showed up at the job and the electrician seemed to have not seen the picture or description I sent at all. I resent the picture and said I was happy to talk to to them if they had questions.

They installed a completely different layout from what I had then sent over twice.

Now they are saying that they won't go back to fix the layout unless we pay the same amount of the original install.

I have used SJO in the past but will no longer be using them in the future. It's disappointing that there was no communication through this entire process and then they are unwilling to work together to get this fixed.
