Partial delivery, old stock, poor customer services and no refund!!!

Extremely poor customer service. I placed an order and received half of the items. Some items received were also old stock e.g. mold on bread. I have logged a ticket via email and to date have not received any feedback. I also chatted to the support via the app. Turnaround times for responses is pathetic. I eventually received a message saying that a refund would be processed on 4th Feb 2021 9:31am but to date have not received any refund. I contacted the store directly and spoke to Mduduzi at Rand Steam PnP. He was unable to assist and referred me back to the app. After several phone calls to him, he eventually gave me Mbalenhle's contact number from Bottles. I spoke to her and she advised that she will investigate and revert back to me. To date I have not received any responses. I tried calling the number back but it now goes to voicemail.
