David, the owner, responded privately to my initial review and invited me to come back to the shop. He offered me a full refund for the cleanup that I had to do following the first tint job, and ensured me that they provide full warranty for all their work. So, we inspected the areas where the tint had some issues and they got to work on re-doing the necessary tints right away. He even saw me half an hour before they opened in the morning, to accommodate my schedule and make sure I didn't have to wait behind other customers.
I couldn't be happier with the resolution of this issue, and I will absolutely refer all my friends to DC Auto and come back here for my future tinting needs. David is a great guy and a dedicated, honest business owner who showed true commitment to customer satisfaction.
