Dead Fly in Debonairs Pizza, Kloof

On 21/11/2019, at the Debonairs Pizza in Kloof, a purchase was made for a Margherita pizza. After eating some of the pizza, I found a dead fly situated between the melted cheese and the pizza base. I took it back to the store and they simply returned my money and said that they have that issue a lot. I asked them why nothing was done if they were aware of the issue, and I received no response. Currently I feel extremely ill and I feel that action needs to be taken by Debonairs head office to resolve this issue. I have photographic evidence of everything and I expect a solution immediately.
