I'm on my third attempt of the day to get through to this company to get the estimate from them, but I keep getting disconnected after more than an hour on hold. No body shop will touch my car without the written estimate from this company ahead of time because of difficulty in getting payment from them. Their adjustor came out two days after the accident (their insured ran a stop sign hit a school bus, went over a curb and into our office parking lot and hit my parked car) took the pictures and watched the video from our security camera and told me I should be able to have the estimate in 48 hours. It's been 3 weeks. Still waiting. Much like other reviews, when I was able to get them on the phone more than a week ago, they told me they had not yet been able to get in touch with their insured. I'm pretty sure she needed to get her car repaired and would be anxious to get everything handled. It's not like there isn't a police report, and a video... Guess I'm going to have to file through my insurance. Worst company ever.
