I had State Farm from the time I started driving at 16 until last year. Their claims were paid promptly and fairly every time . . . BUT . . .
My agent retired, and I was shifted to a new agency. Quality of service went down drastically. Then that agent retired, and again I was placed at a different agency. This agency was horrendously bad. Getting a vehicle added to the policy and another removed took several phone calls and a personal visit to their office. That had always been accomplished in the past with a quick phone call.
Then I didn't receive a renewal notice for my policy when it was up. State Farm has an endorsement they offer (or offered) to long term policyholders called Guaranteed Renewal. That endorsement was added to my policy some years ago. I called the agency to ask why I never received a renewal notice. Told her I had to maintain coverage. A bit later she called me back and informed me that State Farm had cancelled my policy. I said that's not possible, I have the guaranteed renewal endorsement. She said that they had no record of that and that my policy was cancelled. End of story.
Wanting to maintain coverage, I immediately called a local Allstate agency. They were very helpful and I had auto coverage immediately. I told her to also get me a quote for home insurance since State Farm had canceled my auto policy (4 vehicles) they no longer deserved any of my business. She set me up with a policy right away.
A couple of hours later I got a call from the horrible State Farm agency. They had "made a mistake" in canceling my policy because I had the guaranteed renewal endorsement, and they would be happy to reinstate my coverage. I told her no thanks, I've already paid Allstate and set up coverage with them.
Now, getting to the chase (finally); when I had my accident on New Year's Day Allstate took VERY good care of me even though the other driver was at fault. They paid my claim promptly and then collected from the other guy's insurance - guess who - State Farm. They sent me an offer for $10K MORE than I had paid for the vehicle and direct deposited it into my account. They have also paid my medical bills and are in the process of getting reimbursement from State Farm. They say I will get my $500 deductible reimbursed by State Farm as well as payment for time lost from work and pain and suffering, but it could take several months for everything to get taken care of.
I took 6 weeks off from work due to my injury, but I really didn't lose any money since I had lots of vacation and personal time built up, so whatever State Farm comes up with is gravy as far as I'm concerned. Yes, I did have pain - a good deal of it, but suffering? Meh.
