Rocky Mountain Auto Body

DO NOT USE THIS PLACE! EVER! RUN AWAY!
I needed a replacement rear bumper and was going through my insurance. I contacted Rocky Mountain since they were much closer than my insurance place, and they set it up for me to come in on Friday, get a rental down the road at Enterprise, and pick up my car on Monday. They said they’d cover my deductible, which was great.
I picked up my car Monday and their paint matching is terrible. The paint on the bumper is much darker than the rest of my car. When I called to complain, they said I’d have to get my insurance company to cover painting the entire rest of my car to match. That is just not right — they say they specialize in color matching, but didn’t match it well at all! My insurance will not cover any further repairs since I didn’t use their shop, and Rocky Mountain said it’s not their fault, so I’m stuck with a too dark bumper which will definitely affect the resale value.
Rocky Mountain told me to leave my rental car there when I picked up my car, so I called Enterprise and told them I was leaving it there which they were fine with. When Enterprise picked it up the next day, the front tire was making a clunking noise — NOT the way I dropped it off. They filed a damage claim against me even though there was no damage at all when I left the rental at Rocky Mountain. Enterprise also told me that the car had 68 miles on it from when I rented it and ¼ tank of gas. I dropped it off after using it for only 21 miles and it had a ½ tank of gas. So the guys at Rocky Mountain decided to go joyriding around in my rental, damaged it, and now I’m getting stuck with the bill.
In addition to all that, my car had a candy bar wrapper and a unsmoked cigarette in it when I picked up (on the passenger side — the damage to my car was the bumper, so why were they inside my car?), and about 80 more miles on it than when I dropped it off. So apparently the guys at this shop like to use their clients cars without permission, and whatever rentals are left there too. I will NEVER use them again and highly suggest no one else does either. If I could give them 0 stars I would.
