Flies in Meat

In last week me and my wife went to buy meat at the shop and when we wanted to use the meat, a dead fly was inside the meat...I RETURNED the meat and demanded my money back....the person who assisted me advised they will advise the Butchery manager, up until today....NO Phone call from anybody at this well established company.....I mean really NOW!! If we did not see the fly inside the meat we would have food poison now. This left a real bad taste in my mouth about PnP.
