Rotten meat

Yesterday, 1st Oct, we went to the Checkers hyper in Scottburgh & purchased some items for a braai as we are on holiday in Scottburgh. After cooking the pork chops and mutton sausages I was horrified to find out its off. There's a horrible smell and taste to it but looked very fresh on the shelf. I tried over 15 times to phone the branch but the landline doesn't even ring. This is terrible service
