Best Matte Finish in Phoenix AZ

First Onsite started drywall on a project last December, but left everything else unfinished. They tried to tell me they needed to replace my entire upstairs floorboards even though only a few boards we're damaged. Replacing my upstairs flooring would have resulted in a minimum cost of over 1,000 in excess parts alone. When I located the replacement model, the technician told me the model was out of stock and if he found it the tint would not match. While I was being ghosted by First Onsite, I found another contractor to replace my floorboards using the model I found and it was a perfect match. Months later First Onsite tries to bill me for repairing everything when all they did was drywall. I sent them documentation of the unfinished work and requested a corrected invoice. It took them two months to send an updated invoice and the new invoice still included costs for things that were not done. Though I was promised an updated invoice a copy months ago I still haven't seen one. In the meantime they have tried to issue a lien on my home twice. Both times I have had to contest the lien referencing the unresolved billing issues. My experience with this company has been incredibly disappointing and unnecessarily stressful. It is nearly the end of October and my billing issues are not resolved. I'm surprised they have 4 stars. Maybe they treat companies better than people. 11/5 update: this matter is now resolve. Updating review from one star to two stars.
