I've got an excellent one. I bought a pretty expensive piece of furniture and had it delivered. My car was parked out front and their truck was parked on the street next to it. After the delivery, I hear my alarm go off so I run out there an see their truck pulling away from my car. I figured it was the truck's engine that set it off. The next morning I come out to go to work and find a foot long, straight crease in my bumper and a HOLE in my fender where the crease ended. I immediately call the delivery company and complain and they totally deny it. So I call my insurance company, they tell me to get an estimate. What's the first thing the guy says at the body shop? "Did you get hit by a big truck?" LOL. The damage was up too high for it to be a regular car, this was obvious. The estimate is pretty high since they have to replace both the bumper and fender and blend the whole front end.
My insurance company contacts the delivery company and it turns out, their insurance is with the same company. At this point, my insurance company doesn't say much and they will handle it as a hit and run claim and I will have to pay my deductible. I tell them NO WAY that is going to happen. I KNOW it was the delivery truck that hit me, even though I can't
really prove it. Now that they know it is the same insurance company, they don't want to deal with it, because they won't get anything out of it. I literally argued with them for over 6 months before they got tired of it and finally waived my deductible and fixed my car.
The best part? The idiot who backed out of his parking spot and hit me, hit me in the same spot that had been repaired from the above accident just a few months earlier.
Fortunately that one was minor and was able to be pulled out by paintless dent removal.
