Pizza Hut shady

Pizza Hut is running a black Friday special where if you spend R200 or more you will get a 50% discount, when I went there they told me it's only for single pizzas and doesn't include ordering any of their specials, I didn't order anything it was a waste of my time they should of been more specific when advertising it's a rotten way to waste a persons time , last year they ran the same special and it wasn't a problem but now it is and they were shady about it
