Pick N Pay Online appears to be a ****

Hi, can anyone help, I'm out of options and been advised that legal action, creating a social media storm, contacting ombudsman is my only option. I placed an order and paid on 30 Nov as I had a large dinner party scheduled 2 days later. Order number # *** No order was delivered and after many hours holding for a call center that doesn't answer and many emails to customer service, 3 weeks later I still don't have the stock I ordered, and I still don't have my money back. They've acknowledged, apologized and give me a multitude of reference numbers but that's it. I'm out of options and been advised that legal action, creating a social media storm, and getting public resolution via ombudsman is my only option. Alternately I'm told that I can declare a dispute with my bank to have the money forced back to my account, after opening a case of ***** at the nearest police station. Please can anyone advise what course of action I should adopt next? Apparently, discussing this at our various community forums, this not the first time Dainfern, Fourways, Lonehill, Helderfontein and surrounding areas have experienced this disgusting service, so maybe a class action? I have asked various forums to contact me if they've also had their money taken without delivery. Thank you Pick n Pay for spoiling my dinner party of 10.
