Spoiled chicken from Pick n Pay

On 13 July 2022 I ordered groceries from Pick n Pay ASAP for delivery. The items were timeously delivered; however on unpacking my items I noticed that I had been overcharged for the chicken, I ordered 4 trays, the price on the app was R48.99 per kg and the item price was marked at R63.99 per kg. I proceeded to call the ASAP call centre and was advised to take pictures of the items and send to them. Whilst attending to the request I smelled the chicken being foul and I reported this to the call centre agent who apologized profusely and advised that a driver would be dispatched to collect the spoiled chicken. A few phone calls later and still no driver called at my home to fetch the chicken. I called the call centre the next day and they advised that a driver would be sent to my premises the next day to uplift the spoiled product and only then could a refund be effected. I proceeded to call the Pick n Pay at Midlands Liberty Mall in pietermaritzburg, as this was the store that the groceries were delivered from and spoke with Dino, the Store Manager. He advised that he was unable to assist as the items were ordered online and I would need to deal directly with Pick n Pay ASAP. I pointed out to him the the spoiled chicken was supp**** from his store; and he advised that I am the first to complain of same. The driver fetched the items on the 15th of July 2022 and I have email confirmation that a refund would be effected into my bank account, which to date I have not received. I have emailed the consultant regarding the refund and have received no response. I am most perturbed by the service received from Pick n Pay as to date I have paid for items that were spoiled, incorrectly priced and no apology from Pick n Pay for the inconvenience; alternatively distress they have caused. I am most upset that as a customer, I have received such poor service from such a major retailer.
