Received cold food

I had a bad experience at Steers Comaro crossing today at 17:58 and received cold food. I bought a king steer burger with medium chips. Chips were fresh and hot. However, both the bun and the patty were cold. So cold that I could not finish it. I made a call to them as soon as I discovered and was told to call them back since the manager was out. When I said they need to call me back-they hung up on me. I am obviously not happy about this.
