I received the wrong order again

I went to Mcdonalds in Pretoria north (Rachel de Beer) on Friday evening with a friend. I ordered to BBQ doubles and small fries. To my surprise, When i opened the burger the next morning to eat, it was a SINGLE chicken patty. I am so disappointed again. i paid for 2 Beef Patties but only received 1. the burger didnt even have lettuce, cheese or tomato. this is not the first time i receive the wrong order at this mcdonalds. I'm so furious!
