Disappointed 1557

Placed an order via the app. At 18h35 on the 24/03/2020. Paid via my debit card. Received an sms with notification of order number : 1557/404193 With a promised delivery time of 19:35. Time of delivery expired, I tried calling the store to enquire about my order, several times, only to ring incessantly without being answered. Same evening i sent a contact me on their website, then i sent various emails on their website stating that i will send a complaint to "Hello Peter" Next evening i called the call centre asking what's the problem. The lady said that she will escalate the problem. To date I have not received a call from Nando's, nor a refund, or apology for their shoddy service. All i want to know is when am I going to be refunded?. I'm so irate for that reason alone. Yes i can understand that lockdown was effective from the 26/03/2020. But they want to get rich on money they haven't earned. I want answers. A simple apology will not do. If they can't handle the heat in the kitchen, then please do me a favour and get out
