SHELLY BEACH PICK N PAY

I absolutely appalled by the quality that Shelly Beach Pick n Pay provides its customers. Yesterday i went to purchase burger patties for dinner. When i scout the meat section I found meat that had expired that was been sold for a reduced price. This meat had already began yellowing. So I decided to take a a fresh Burger Mince patties that decent. I got home and put them in the oven and 10 Minutes later they had shrunk down to the size of a key remote for a gate. I am really upset and customer service is even worse. Customers are waiting 10-15 minutes in line for assistance due staff have personal chats. I wouldn't even come to this store but its the close store to me.
