Fly in my food!!!

We bought a Chicken Mayo which seem to rep nice & put on ices in the Deli when the shop was about to close. To my horror when I found the fly in my food. The horror was when the store manager (Melony) or something as she didn't have a name tang) seem to think all was ok & all she could say was that some1 is going to bring your money now... like really. No apologies.... If I wanted to keep my money was not going to waste my time and walk all the way to that shop. This Manager really needs her customer services check up very fast.
