Poor, appalling service delivery from Pick n Pay Customer care

I usually buy the Pick n Pay branded items. For a while now the long lasting carton PnP milk does not last long then it goes off soon and the carton top is flimpsy and leaks and breaks off easily, so one has to be extra careful with same. Last week I wrote to their customer care, included pics I took and receipts. I received an e-mail from a Wendy Ngqwebo from Pick n Pay apologizing for the inconvenience, indicating my complaints were escalated to the various stores and I could expect a call from these stores. To date NO ONE from any of the stores contacted me, but received an e-mail from customer care closing the matter as COMPLETED. I again wrote to them and received the same e-mail. I find this totally appalling and do not appreciate the poor service delivery from Pick n Pay staff!! They are quick to overcharge on their products, but not very quick to act and correct on their poor quality products. Their standards and service delivery have really dropped tremendously. I am definitely taking my groceries, etc. shopping elsewhere, to a better, much cheaper Retailer, who will give me better services and better products. Close all your doors Pick n Pay if you cannot live up to your name. I am very disgruntled with them
