Their employees painted around parked cars at the ...

Their employees painted around parked cars at the school I work for without communicating to anyone that they would be painting that day/time. When I found paint, scratches, and chipping to my windshield from the blower machine they use before painting and then the paint machine after, I immediately informed my associate principal who called for a supervisor to come over and speak with us. In total, three employees of the school had damages to their vehicles. The supervisor was incredibly rude and dismissive about the entire situation and even said to me "if you're just looking to get a free car wash out of this, I'll pay to get you one."
I'm extremely disgusted by the entire company's lack of professionalism from top to bottom. I was put in contact with a gentleman named David Darden who is slow to respond, if he responds at all. He does not fully address issues and does not provide any follow through or resolution.
I contacted Henrico PD to get an incident # for the situation and had my school pull the video footage of the incident since I park in line with the school cameras. I provided more than 80 photos of the damages to Mr. Darden along with the incident #, but at the time, I was waiting for the footage. He advised me to get an estimate for the damages, which I got three of. I also offered to get additional estimates from other auto shops if they had one they preferred. I was told that would not be necessary.
Eventually, I was contacted ONCE by a woman named Tanja Szardenings from Gallagher Bassett stating she was their insurance representative. She said she was only provided with two of the three estimates from Mr. Darden and none of the pictures. I tried sending her the pictures myself, but her email address does not allow for files over a certain size. Because of this issue, I am unable to send her all of the photos or the video. I have emailed her numerous times and left dozens of voice mail messages for her asking to return my call.

What irritates me the most about the entire situation is that their employees painted around teachers' car without any regard for their vehicles.... but the employees did not paint around the contractors' vehicles in the same lot. They had courteous and respect for them but not for us. We would have gladly moved out vehicles for the company if they had informed us.
