Manager extremely rude

I had a very bad experience at Debonairs in Harding, KZN . I went to order pizza and the manager that took my order took it incorrectly. When I got home I saw that I got two of the same pizzas. We went back to the restaurant and stated that we ordered one club pizza and one BBQ Bacon pizza and the manager was extremely rude and arrogant and stating that we ordered two BBQ Bacon pizza. She did not want to fix the order , even though we were willing to pay extra chargers for the difference. She was very rude and we got spoken to in a horrible manner. Very horrible service was received!
