Furious and frustrated

Good Day , I am really frustrated with the service at MacDonald doorways crossing.I placed an order through mr delivery for x2 cheeseburger meals for R30.00 and I received x1 cheeseburger meal with and extra burger. I called and spoke to amanda and kenny . They apologized and said I should call Mr delivery to fix my order because the mistake was done on their side. I called Mr delivery and spoke to Avu she fixed it for me but when the order arrived it was the same what's worse it was now R60.00 . I am pregnant and I placed an order at 2 o'clock and I'm still trying to rectify my order. I am furious .I have images of the order I ordered.
