Reckless Driving, lying and no compensation for the damage to property they caused.

An ADT driver skipped a stop street, crashed into an oncoming vehicle and drove through the fence at our offices. Our security company reported the accident to us, and I was here within an hour (at 6am on a Saturday). There were multiple ADT response vehicles onsite. An entire palisade had been knocked to the ground, anyone could simply walk in from the busy street, we had delivery vehicles parked outside, our entire property was vulnerable and at risk, I was given the wrong contact details to report the damage to, I was promised that they would post guards until we could make repairs, they didn't. They **** about how the accident occurred and said that the person that they hit was at fault and drunk, both drivers passed the breathalyzer at the police station. In fact, no one from ADT got in touch at all. I had to find the details online to make a claim. This was 2 months ago and they have tried to stall and delay and request info that was already submitted, I've submitted a quote, explained that I was onsite for 4 hours, and had to call in staff to make temporary repairs and they continue to ask for more info or documents. How is this not settled by their insurance company after 2 months. They seem to be notoriously reckless on the roads, their own tow truck driver told me that it was the third accident that day in our area. I wouldn't trust this company to keep anyone or anything safe. They seem to be ************ and very experienced ****s.
