Dunked wings/ wings

KFC Tlhabane square I've literally been there for the past 3 days and everyday there are no wings. Is it that you guys no longer sell them or what Monday I went to the self service machine and placed an order for wings and I paid because I thought it's convenient, when I get to the till to collect they ask me if I didn't see the note I'm sure that paper is not even A5 with the no wings order, my question is why not remove it from the menu aker you guys don't sell it anymore even last night same story mxm.
