KFC Mall of the south: Terrible service followed by a "brush-off" from Customer Care

I had a shocking experience at KFC Mall of the South on 30/12/2025 at 21:30. A staff member, Ntsako, stopped me from paying and made me wait 20 minutes to "check stock." During this time, she continued preparing meals for others. She eventually told me there was nothing left, then suddenly "found" enough for a different meal after I challenged her. I logged a formal complaint (Case: CAS-***-D3N2Q4), and the response I received was even worse. KFC Customer Care sent a generic email stating, "an apology has been extended, and no further contact will ensue." This is not a resolution. I was ignored in-store and now I am being silenced by their head office. I expect a call from a Regional Manager to address the blatant lack of service and the way this complaint was handled.
