After 30 years with the RAC I need to cancel my membership. You abandoned my wife and three children when her car broke down. I spent 15 hours overnight in a cold car park waiting for you. Each time I called you, you gave me a different story about how assistance was on its way, but none of them were true. We first called you at 6pm. I finally got a tow home at 9am. How do I get a refund please?
