Old meat

Purchase meat on 7.07.2018 at spar parow valley market street and only discover later that the meat had a bad smell and was not fresh so i return the meat on the 8.07.2018 to the store and ask to speak to a manager only to be told that they dont know where he is and the onther manager is off duty, so the butcher manager approach me and i told her my story about the meat while i was in the store waiting for the manager i took another pack of pork on their shelf and open it juat to show them that all the pork meat on their shelf is not fresh bit the expired sate is the 10.07.2018 which i could not understand. The butcher manager told me that the second meat i took off the shelf is fine but only had i little smell. They tried to cover up the story but the fact is they sold me old meat. The health and safety must seriously inspect that store. This is my 3rd time i had the same problem with this store and wont buy meat products from them again.
