poor services, falls advertising

I have never felt disrespected like this before. on 13/03/2020 around 7:25 - 7:40 pm I order meaty Filla mogul for R139.90 + R10 delivery which I paid for it online. between 8:50 and 9:30 pm, I tried calling this number *** many times to find out why I haven't received my food and I could go through as voice prompt said they can't process my call. I then decide to drive to maponya mall where I placed my order when I was about to park, the delivery man called and he is outside my house and I had to drive back without going to the store and when I got home the guy was not there. I waited for him for another 30 minutes to get to me. when he go there the pizza was cold and the dot was black, I told him that the pizza is now free he laughed at me and he drove off the worse part the pizza had no feta chess which is supposed to be on top. then on the 14th at 15:02 pm I called the number *** and asked to be transferred to the maponya mall store I was advised that they can't be transferred since I am complaining. then I explain my story to the who said she works at a call center and I was advised that they can't help me since I accepted the pizza I was supposed to return it, she said is sorry they that the feta chess was not there and I can't get a refund for getting a cold pizza since they say when the dot is black the pizza is free. what are we suppose to do when the company has falls advertising like this? since I can't get my refund. I have a picture's that i took when I was handed my pizza as evidence for my claim.
