Wrong pizza

I'm fuming as I ordered a Triple Decker pizza at Sam Ntuli. I asked the lady to do half creamy chicken and half something meat. She said she can't do that and I asked her to do something meat. When it was time for collection I discovered that it not a Triple Decker. I told the lady that I said Triple decker not the one she gave me. She called the lady that I paid too and said chomi what did she order she said I ordered Large pizza. I asked her that didn't I say large pizza. She walk away and left me with her friend that claimed to be the manager. I asked her that can she give me an email or cell number of her superiors as she can't help me as a manager. She told me that she's not allowed to give customers the number or email 😒 🙄 😐 😕. Im not happy with their service and you can see that as they friends they always do that to customers. The lady who claimed to be a manager was busy taking out the pizzas from the stove and left me there to say she's calling her superiors. I will never ever gonna buy there as they giving customers attitude and they even calling each other chomi to see that they friends and use to do this. Nxa pathetic service 😠🤬
