Gave me incorrect order. Management were rude, lie...

Gave me incorrect order. Management were rude, lie to my face and argued that they were correct despite clear evidence from the Pizza Hut website showing that they were wrong. The manager actually claimed that their website is irrelevant to them, despite the order being made on.. the website.

Thankfully, Pizza Hut customer support number identified the wrong doings and agreed with me (because I had literal proof) and are now trying to correct this.
