Zinger Wings

I was at kfc at bara taxi rank, the service was very slow to begin with but lucky for them I work in an industry where patience is second nature to me. I ordered Street Wise 2 with 8 Zinger Wings only to get home to find 6 Zinger Wings in my packet. I paid R30 for the food but was given food worth R15. Unfair part is that I could not go back because its a 30minute taxi ride distance. All is all that's bad service because they are gaining more from us.
