Checkers selling mouldy food

Good day, I am so disgusted with Checkers in Eastgate Shopping centre. Yesterday I bought a salad there and it was rotten and mouldy. The bad thing this is not the first time something like this has happened. the previous times I just let it slide put with prices going up you can't afford to pay for off food... this is really ridiculous. I will not recommend anyone to go there anymore the standards has slipped badly!!!
