Rotten Food and Bad Attitude

On the 9th of January my colleagues and i ordered food from fishaways, simple 2 x fish and salad and fish burger. I was told the food would be delivered within the next 30 -40 minutes. An hour later the food was still not delivered and so i called again to check on the order and was then told there was some system error and my order was actually not placed. Had i not called they wouldnt have picked up the error. Even then there was no sympathy i the system was blamed and i had to wait. eventually the food was delivered, it was horrible, the salad had 3 thinly cut pieces of tomatoes and same with the carrot. The worst part is that the lettuce was rotten. I called the store to complain and the manager on duty Mr Mthandazo Nkomo simply apologised and said the salad was according to the standard set by the frenchise. My question is does fishaways expect us to pay money to eat rotten lettuce. When i explained to the manager that i cannot accept an apology he could not come up with a solution and promised to call me in 30 minutes. Till today i am still waiting for the call. It was the first and the last time i ordered from this fishaways and would never advise anyone to order from there.
