Selling expired stock

Good day <br> <br> I went on Pick 'n Pay site with a complaint almost 2 weeks ago with a complaint and have received no feedback.<br> We bought a peri peri marinade and it exploded all over when we opened it. My mother top is ruined and we had the inconvenience of having to clean the whole mess up.<br> <br> I have photo's and the till slip and still no feedback.<br> the bottle was clearly put on shelf with the knowledge of being expired as the expired label was damaged in order for the consumer not to notice the date.<br> <br> I would like to escalate this matter
