Terrible service at Nando's Canterbury

On Saturday, 15th of May, I have ordered two Boujee Bowls on UberEats. One was supposed to be with chicken, and the other one was supposed to be a veggie bowl. When I received the order, both were chicken bowls. I made contact with Nando's Canterbury, and they stated that they'll send a driver with the correct veggie bowl. The line was very bad and the manager's English was quite broken.

The driver got here, gave the veggie bowl, and left. After that, the manager called me multiple times and after that sent me a WhatsApp, mentioning I didn't switch the chicken bowl as we agreed upon, he's sending his driving back to collect the other bowl. As previously mentioned, the communication was bad and this was not how I understood the conversation.

I told him that my son ate the other bowl, he was furious and sent the driver to my house, demanding I pay for the wrong order.

I would like to know if this was handled correctly and if it is expected for a wrong order to be switched, even after an hour has passed? And most importantly what would have happened to the bowl if we sent it back? Would they have resold it?
