I just saved about $400 dollars a year by switching to AAA from State Farm. The coverage for my cars is the same and the coverage for my home is much better (and cheaper) than before. I have a credit card through AAA, roadside assistance through AAA and finally, my insurance through AAA. I could not be happier. On all fronts, AAA has the best customer service I've ever encountered.
USAA use to be a reputable company however in pass years their level in integrity customer service has declined tremendously. Lack of due diligence poor laziness. I am so ashamed for them. I have been a member for over 12 years no more. I am in the process of moving all my accounts and severing all ties. Yes it is that bad. It is time consuming but 200% necessary unfortunately. I will not share each negative and compromising act they did but I do not trust them. If you want your own horrible experience please join and find out.
