You'd think that your own insurance carrier would want to make you whole, right?
Right?
When, about 2 years ago, my wife's Mazda was totaled by some jamoke running a red light and turning into her, I thought the same thing. The other driver was cited and 100% at fault.
I pay a lot for insurance. I use a broker and buy good policies. I carry auto, motorcycle, homeowner, inland marine, and various business insurance packages. "Cool," I thought, "I'll just file with my carrier (Safeco / Liberty Mutual) and it'll be easier."
Feckin' NOPE. Not remotely. Safeco gave me the runaround for well over a month: Giving me absurdly low valuations on our car, providing "comps" to support their valuations that A) had twice the mileage, B) did not have the options ours did, C) were hundreds of miles out of state, and D) **DID NOT ACTUALLY EXIST** when I called to inquire about them (and call my carrier's bluff).
The adjuster ghosted me and generally wanted to play silly buggers; my own insurance carrier jerked me around for 7 full weeks! I brought my broker into the fold. The adjuster's manager finally reached out but with an absolutely anemic increase in valuation. This was during COVID so the used-car market was absurd; they wanted to give us pre-COVID value, rather than replacement cost. (How do I know what replacement cost was? I found the exact same car that we lost -- very nearly the same mileage, same trim package, even the same color -- and bought it in cash from a reputable no-haggle dealer.)
Ultimately I ended up filing with the other party's company. This was still a headache, but eventually they played ball and reimbursed me for the full purchase price of the replacement car.
Consequently I fired my insurance carrier. I involved my brokerage, who (I believe) has stopped recommending that carrier as a result. I also wrote a rather detailed e-mail that copied my broker, the adjuster, the adjuster's boss, and the adjuster's boss' boss explaining why they were losing my business.
Screw them.
