Pic n pay maponya now selling expired foods to the public

On the 29th of July 2020 i went shopping at the maponya mall Pic n pay and one of the items I purchased was the no name French polony from the store the packaging was marked best before 21/08/20 batch no:2062 but on opening the packaging this morning the first two slices seemed normal and were consumed as we went for the rest we realised they were now green even though they were refrigerated since the day of purchase. I'm completely disgusted and disappointed and hope my complaint will be taken seriously.
