Missing item, condescending service and a resolution tied to my next purchase

I ordered food through the Spur app, including a 16-wing meal, but received only 15 wings.

When I called to report this, I found both the person who answered and the manager Conrad cynical and condescending in their tone. I was told the missing wing would be added to my next order.

Why should I have to place another order to receive something I have already paid for? There is no guarantee I will order from this branch again, especially after this experience.

The issue is not simply one missing wing. It is how a straightforward complaint was handled. A sincere apology and a resolution that did not depend on another purchase would have made all the difference.
