Buying expired goods 3 Times!

The Engen at Cnr The Hills St &, Durbanville Ave, Durbanville, the garage is fine but the shop is terrible have had 3 experiences of buying expired goods , expired yogurt was at first then it was a sandwich that was made in June and the frozen and sold in December on packaging it states max frozen 3 months and they sold it in December , I stopped buying goods at the store and just used the garage as its on my way to work . I decide Monday morning to buy a coffee an americano with milk and received a coffee with milk chunks in it that looked like cottage cheese I told the server and she made a new one with fresh milk, just to be disgusted to see that there is still little chunks left which mean she did not even bother to clean the holder for the milk I will never use that Store at that garage or recommend someone to use it.
