If you dont want to eat order at Gandhi square Nandos

I called in to place an order at 12:00 which was a full checking and 2 sides for 2 people sharing. At 13:00 the driver came to deliver when I was about to pay, he laughed and told me that he forgot my order and he promised that he will call for someone to deliver. I waited from 13:00 till 14:30 no one called me to inform me if the order is coming or not. At 14:35 I called them and I spoke to Khanyi and told me that the deliver guy sent her a whatsapp message but she only saw it later, and my question was who's fault is it cause I am hungry and no one called me to inform me about that. I told her that Ill come at 16:30 to speak to the manager I want the manager to tell me whos fault was it. The driver called me to apologise just because I said I will speak to the manager, did he call me before to tell me that he will bring the order no he did not. I went to the shop at 16:30 I spoke to freedom the so called manager who was so casual about the whole thing and was told by the delivery guy that Pamela said she will handle me. Then that was the escape for Freedom apparently Pamela is also a manager, had to wait again for Pamela, everything that you have to do at Nandos is to wait, wait for your food and wait for their manager, after 10 minutes he only realised that Pamela is not coming only then he asked me if I still want my order, how dumb is that? Clearly they take their customers seriously, thats why their phone is off the hook when I tried calling to ask about my order, only at 14:35 I was able to get through. THEY MUST JUST PULL THEIR SOCKS OR LET US KNOW THAT WE MUST NOT ORDER FROM THEM.
