Terrible attitude from managers

My sisters and I ordered a pizza last night from Debonairs, Walmer. When the pizza arrived. there was literary no chicken, no mushroom and almost no debonairs sauce on the chicken.

We called them and told them we are very unhapy with our pizza. We were directed to the first manager called Marizza, orMaritza or Mariska, who asked us to send photos on her whatsapp. Which we did. She then blue ticked our message. When we called back she said that shes waiting for her manager, and her managers manager and so on to confirm whether we can get an exchange on the pizza. 15 min later. We called back to find out that she has left now there is another manager on duty called Paul . Before we could even give the full story he started shouting at us and giving us attitude. He told us he's not gonna change the pizza if we have a problem we should take it up with the head office. we then told him we will never ever use the Walmer debonairs as it was our first tie ordering from it and he is giving us attitude.
