Pizza Hut

I've only been to this one twice but both times the pizza was very good. I do, however, have complaints about their app and website not submitting orders when you click to submit (and/or says my card is expired when it displays right on the page that it doesn't expire for two more years) and so, as a result, there is no pizza ready, the online order special or discount is not tallied and neither are my rewards points. This has been a consistent issue for years. Am I the only one? If not, someone in IT needs to do their job.
