I had completely the opposite experience - our service with USAA was terrible. My wife's father was in the military so she had USAA for everything when we got married. We got a cheaper quote from another company for auto insurance, and when we tried to cancel for USAA they refused to do it and got belligerent on the phone, claiming that "we are the best" and "why would you want to use anyone else" and that our other quote "must be a mistake." It took half a dozen phone calls before we were able to cancel the service.

Their credit card (which she still has) isn't much better. Huge delays posting payments, and the customer service has a huge chip on their shoulder whenever she needs to call them.
