Worst service

Hi debonairs pizza is by far has the worst service imaginable..I cannot express how frustrated i am right now. The manager portia shlongwanwe from the phoenix branch put the phone down on me whilst talking to her. They never ever have the required ingredients. I asked for something to be cut out of my pizza and apparently it comes pre mixed. Does anyone even check the health and safety of this store, esp if you already have pre mixed ingredients that you can't change. I only wanted plain cheese in a popit. How hard is that. Extremely frustrated
