Oh my wooooord?! Fly eggs in my food !

I bought Spar \CC Chicken Bites"today and had to through it all away as I found fly eggs on the nuggets. I actually took a photo of it because it was sadly so disgusting. I work in an environment where I cannot just up and out to the store whenever I feel like it so did not have the chance to go back as I don't think Spar's chicken nuggets will ever be the same again in anyway? I realise that their is a problem with ready made food as you sometimes would stand in front of the warm server and see flies flying in and about the food when a staff member is dishing up their has to be some control or even just an effort. The staff would be so used to the flies that they would not even try to distract the flies away from the food but simply carry on dishing up. The R/kilo is also just as shameful as the fly eggs but if it is lunch time you don't mind paying the asking price on the condition you get quality in return with no fly eggs on the side please.??!!!"""
