Mac’s Custom Cabinetry

I was scheduled to have Living Room Fireplace nooks installed in my home by Mac’s Custom Cabinetry. Half of the work was completed, and Mac’s was scheduled to come over and finish the job on the following day. Upon the owner and his employee leaving the first day, I attempted to plug my cable box which is pre-​wired behind the walls and up to the TV back in and noticed it was not working. I tested the issue and discovered that plugging the cable directly to the TV worked fine, proving that upon the installation of the cabinets, the HDMI connection from the wall outlet and up to the TV got damaged in some way.
When he came the next day to finish the project, I brought this issue up with the Owner and he claimed that he was not to blame for the wiring not working even though he had to remove the pre-​wired plates from the wall in order to install the cabinets. He then proceeded to try and claim that it was in fact my fault that the wiring was not working, and that I must have done it myself. The problem with his claim is that the TV functioned fine for years and even up until the morning of the install before he worked on them.
I had already paid half of the total bill, and refused to pay the rest until the matter of the pre-​wiring was resolved either by himself, or by bringing in a 3^rd party to fix, and then having him cover the bill. He refused, claimed it was in no way his responsibility and proceeded to leave the job site and took my cabinet doors which he had already installed off their hinges and with him.
I have never heard of a company obviously damaging something and then denying all responsibility and in fact blaming the customer for the problem
Please, do yourself a favor and avoid this company and its owner at all costs. They are truly an embarrassment to themselves and other contractors.
