Bad service

I was just at Pananrottis in Potchefstroom mall. The waiter came to take our order and I ordered The chicken livers but please do not make it too spicy and I mentioned very mild. On the menu it says creamy chicken livers so I really was looking forward to that and because I was really hungry. When our food arrived the chicken livers was in a tomato based sauce. I said to the waiter I am sorry I am not eating this. The manager came over and said my waiter says you are unhappy what is the matter because our sauce is a standard sauce but if you want we can ad some cream for you. She offered to replace it and I asked for the menu by this time I was so revolted by her attitude and dirty hair and the way she talked as if to try and intimidate me I said just give me the livers I'm really hungry. I started eating the livers and there where NO spices in there it tasted like it came out of a KOO tin! it was revolting and cream added would have been worse!!! So I picked the plate up and put it on the table behind me. I was livid!!! She didn't even get my order about spice right! Manager then told me nobody tried to force it down me. I told her take it off the bill and I left and went to spur
