Nando's Pathetic, care team management team, Still No response after 2 weeks and they say they care about their customers, Loyal Customer or not they Don't Care

I am highly ****ed off with the Nando's at Sirkel Rd Shops 20 & 21, Shoprite Centre, Eldorado Park, Soweto, 1813 I called and placed an order for collection and told them what time I was going to collect as I am working from home and then when I get there and produce my order number I was told to wait in the Que with the people that are waiting to place orders. I was shocked, they have an app to place orders and also have a number to call and place an order for delivery or collection. I want to ask what is the purpose or point of calling or using the app to place an order and waste airtime and data only to be told to wait in the Que with the people that came to order when you have just come to collect your. I thought that I would communicate with Nando as I was upset and still am. Then call their customer care and even logged this on their Facebook and they asked for my details and assured me that they would call me to resolve the problem. Apparently they have a care team and management team of which I was told would contact me and that is why they wanted my details. That was 2 weeks ago and still no contact from either their so called care team or management team. I am very disappointed with their service, their care team management team and I was if they can treat 1 of their customer like this how are they treating their other loyal customers.
