California Casualty changed my auto policy 4 times without my consent, only notifying me by mail 2 weeks or so after each time they changed it. Of course, they revised my premium up every single time. One of the times, they automatically added a 16-year old male driver to my household without my consent, which basically doubled my monthly payment. Another time, they changed my coverage limits without my consent, which also increased my monthly payment.
DO NOT USE CALIFORNIA CASUALTY. They will try every trick they can to squeeze as much money as possible from you. Luckily, I never had to file a claim with them.
I switched to USAA, and have had ZERO issues. Definitely a learning experience.
