Appalling Service and Rotten goods

The Pick n Pay at the Pavillion has been the worst Customer service experience ever, we had bought chocolate Santa's for our kids as they were marked down because Christmas had long passed, the chocolates were covered with what looks like cobwebs and there was an insect crawling on the chocolate which was covered by foil, unfortunately of the 4 chocolates we bought 3 were taken to school by my younger kids and consumed which lead to us having to deform them as clearly the chocolate was stale and rotten even though it had not reached the expiration date, we took it back to Pick n Pay and a Manger by the name of Beryl who was supposed to have assisted us, she dragged her feet in getting back to us with proper explanation and resolution, when we asked her to call us back as we had missed her call she didn't bother and then went of leave for a few weeks this was around the 25th of July, we went back to the store on the 15th of August as we had no feedback to find that she has returned to work the day before and clearly we were not a priority as she still hadn't make contact with us. When we approached her on the 15th to find out what was happening she said had stories upon stories and tried to shift the blame to the manager on duty while she was on leave, nonetheless she said she would call their head office and make sure someone contacted us the very same day if not within an hour, today is the 19th of August and nobody has contacted us, we have tried calling her and she doesn't take the calls and we have sent her a message on WhatsApp with the video on the bugs on the chocolate and she has still just ignored us, this service is absolutely putrid and have total disregard for the affects this could have had on our kids and many other people who had also bought this item which they only took off the shelves when we made them aware of it a day or so later, the manager Beryl **** to our faces just to get us out the store and it seems never intended on property resolving this matter because she gave us the money for the chocolate back which we told her we don't even want because they need to also contact the suppliers and rectify this situation plus the money I spent having to deworm my kids, absolutely appalling service and so human element shown by the manager, I would like to see if 1 of her kids ha to eat that rotten cobwebs bug infested chocolate!!!!
