Pick n Pay - I was sold rotten samoosas

On Tuesday 31 August i bought 3 samoosas at Ockfields pick n pay in Boksburg. I ate 2 by the 3rd one I realized the chicken samoosa is rotten. I still have the receipt and I called them say day since I was driving thru and dont stay in the area and there was no way I could go back. The manager Hope told me he'll talk to the supplier and they phoned me the following day. They both shifting the blame and claiming to sell fresh samoosas when they clearly poisoned me with rotten stuff and the supplier offering me more samoosas. I still have the rotten samoosa and the receipt and no one is coming with a solution.
