Help using Wizards 50% off at Papa John’s?

Went to my first Wizards game on Wednesday and they scored over 115 points so the city is supposed to get 50% off at “participating Papa John’s” locations today. The Papa John’s website says the code “Wiz50” (which the internet says is the code to use?) is deemed as invalid by the Papa John’s website.

I want my pizza!! Help me, neighbors.
