Poor product production

Good Evening

I hope this finds you well, I am very upset with the service I received from Debonairs IXOPO, I ordered a on the triple via the app for delivery, one of the pizza's I ordered was "peperoni and olives" and when I received my order all my pizza had was Peperoni and not a single olive...I Should some how think they should have communicated with me if the had run out of Olives!? Which would then give me a choice to change my pizza choices....
