Report Car Assistance through USAA

My car died and I got car assistance through USAA to get a jump which led to a really uncomfortable hour dealing with the guy that came to help. Afterwards he asked me for a tip and gave me his phone number. I don't think this interaction was appropriate and trying to find out ways to report this to USAA. I don't really see anything on the app where I can report it and the phone directs me to an office that is closed. Does anyone have any advice on where I can report this.
