PnP disregard of compaint

I sent a complaint to Pick and Pay customer care in December 2022 regarding an item advertised for Christmas in their catalogues and online that wasn't available at 5 stores. I received a response on 27 December 2022 with a reference number stating I would be contacted and to date now 16 March 2023 I have not been contacted. This was the complaint I sent them; I saw the PnP Porchetta wrapped in bacon advertised under the festive meats and I'm extremely disappointed that I have been to several stores and I have been told that they have not received any stock of this item. I've been to Longbeach mall twice, Kenilworth, Blue Route, Constantia and PnP Main Road Fish Hoek branches and told the same thing. So it's been a complete waste of petrol and I've been sent from pillar to post. I fail to understand how this is advertised and then not available at 5 stores.
