KFC branch constantly denies having midweek specials

We are regular customers of KFC in the durban area and noticed that the branch at bridge city (drive thru) constantly denies having their tuesday specials although they are advertised on television weekly. Its upsetting when a customer drives to the store with an expectation to recieve good value for money, only to be turned away twice with blatant lies for the benefit of a greater profit margin. We are seriously considering not supporting this franchise any fuether. The fact that this has happened twice indicates that they are fooling most of their loyal customers as well.
