Bad customer service, burnt food and not getting back to me as promised

I placed an order at approximately 13:15 online for delivery from Rivonia Drive Through and when I did not receive my order by 14:05 as on the app the lady I spoke to gave me such an attitude and told me there was nothing that they could do because they don't have drivers. So will have to wait and told me she would look for the driver and hung up. I will never order there again. I always choose Sunninghill even though it is a bit further but at least they call you to let you know that there is a delay. I have never had issues with them (I have proof of this on my order history). I have called them 7 times after that and each time, after choosing option 2 (following up on order), the phone dies. But its picked up when you want to place an order and suddenly they cant assist because its a different department. I even called their 086 number and two people promised to call me back and never did. When the food finally arrive? It was BURNT and my colleagues could even smell it. and the second Hot Pot barely had rice in it. *** is my order number. I am at work and now expected to leave everything and chase after the food that I paid for! and beg people to give me the turnaround time. Even the second person who said "I can't speak for other people but myself" and I will call you back has not called back! 25 minutes later
