Debonairs cannot do simple mathematics and argues with customer

I tried to order 2 pizzas. The person behind counte gave me the wrong price. She said the price was over R30 more than it should be. When I pointed it out to her, she said the customer is confused. I had to show her own menu to her to prove her wrong. The cashier's name was Nozipho and the manager was Nomfundo. They eventually got angry and Nozipho walked away. I am fed up with the useless staff at debonairs queensburgh. This is not the first time either. Ive complained about late delivery, missing items, and best of all, the one time they didn't have cheese! Imagine that! A pizza place without cheese!
