Pizza Hut

The Pizza Hut in Banning, CA has some of the worst customer service I have ever seen. They do not deliver what you order most of the time and when you call to complain, they lie to you and say that they tried to call. They have the correct phone number and I have not received any calls. I have tried severe undertipping as well as complaining and they still continue to run their business as if they are the important ones and not the customer. The delivery guy was late to work according to the lady on the phone and yet when he arrived a half hour late, he blamed them. This all happened today January 1, 2016 and my New Year's resolution is to never order from Pizza Hut again. How can anyone run a business this way?
