Worst service - PATHETIC - USELESS

I don't understand what is going on with Nandos these days. I order from them at least 5 times a week through the call and collect option as it is convenient for me to just stop, pay and collect on my way home. Today is the 5th time they got my order wrong and I had to wait for an extra 30 minutes because they had to redo the order. I don't understand what is so difficult or complicated about taking a order over the phone and giving me what I asked for and pay for. Again, today, I ordered a full chicken, cut in 4 half extra hot and half mozam paprika very well done with 3 sides. I asked the woman on the phone to repeat the order of which she even repeated what I ordered correctly. When I got to the store and paid I was handed my slip only to find my chicken order was wrong AGAIN!!!!! The slip and the chicken that they wanted to give me is Tangy Tomato..... Like seriously ***?!?!? When I asked the manager why the service is becoming so bad all he could say was "I don't know who took your order" . Now I'm sitting here waiting for my chicken to be redone when I am suppose to be home already after a long and hectic week. Really Nandos, we love your food so much and your Horizon store was by far the best but the service has become *** and no one seems to care. What is the point of having a call and collect service if the idiots taking the order can't even get it rite. Please sort out the pathetic service and properly train the miserable people working behind the counter that take the orders.
