Nando's and it's appalling service

I am DISGUTSED by Nando's in Meadowdale, I was charged for an order which was not complete when it was delivered to me, and I paid the full amount of that order, granted I should have checked my order before paying for it, However that is not my main issue.

My issue is the driver who promised he will bring my order, I took down his name and he said he did not have a tel number, fortunately we have access control at work and he must have forgotten that he wrote his number there, I am still waiting for him. Then I decided to call the call center and boy was I transferred from pillar to post, I called 7 times and each time I was transferred to an unavailable number, and I would tell the call center staff this and they did not seem to care, on the 8th time I called I was told an sms would be sent to the branch and I would receive he rest of my order, I had to wait for over 2 hours and I am extremely unhappy about this.
