woolworths **** flies and lamb

I went to Dainfern square, woolworths yesterday afternoon looking to buy lamb, to my surprise when I pick up a tray of lamb I see a huge fat green fly in the lamb, it was utterly disgusting, it has put me off completely, for the price and so called standard of woolworths, to see something that upsetting and disgusting is really disappointing! Is the woolworths standards dropping so pathetically that there's now flies served with their lamb? I am utterly annoyed and put off by the sight of what happened, was the meat borderline going off which is why it attracted the flies? If this is the case and the standard that woolworths is operating, then they honestly shouldn't take pride in being "above the rest" cause in my opinion they aren't!
