Hygienic standards

I visited pick n pay Newtown junction during lunch time 2 weeks ago wanted to grab some thing to eat at the deli so wanted fried fish but there's was a dead fly on in l alerted the lady who was there to my surprise she just removed it and left the fish there and again on the 5th of December there l was wanted to buy red meat again a dead fly wrapped with it ended up buying roasted chicken which was on promo for 2 at 100 to my disappointment it was rotten with a terrible smell so lm concerned with the level of hygienic standards of such a big retail store, sent any email to pick n pay customer service but know one has bothered to contact me l just want my money back
