I've been fucked far harder by State Farm than that.
Car gets stolen, after two or three months of arguing back and forth what the car was worth, finally got an offer for something close to what I thought it was worth. Still less than I wanted, but at this point, the extra few grand wasn't worth it to me.
In those few months I had missed chances to buy quite a few cars at a good price that really had my interest. I missed buying one from Akron by all of a week.
A deal was worked out that I would pick up a car from Alabama, the guy was driving to Nashville that weekend anyway so he said he'd just bring the car on a trailer and we could meet half way. This sounded ideal, so I called State Farm to verify they weren't going to increase my rates when I picked up the new car. Being informed they wouldn't, I went and picked the car up.
Two weeks later I'm dropped due to being "high risk", my speeding ticket situation hadn't changed in over six months, yet they claim it was due to that.
At the time I was driving a beater 1G DSM because I was tired of worrying about leaving my car somewhere (which didn't work, some clown still stole a busted ass head unit out of that car, awesome). I had $1,200 total in this car. When I was dropped as high risk I called another insurance company (I don't remember which off hand, I called quite a few) they wanted $450/m for LIABILITY. In three months I would have more money in the car in insurance money than I did total cash to own it.
In the end I got to pay high risk insurance for 2+ years due to someone stealing my car.
