KFC is terrible

KFC has the most unhelpful, uneducated staff when it comes to their products. KFC website is misleading and false and when i told them that as a customer i can demand what is advertised and for that price they tell me they cannot authorize any kfc to issue me with a meal as advertised on their site. The scenario: I order a boxmaster reg meal as advertised for R64.90, it contains 2 pieces of chicken, a coke, chips, the boxmaster wrap. then right next to it is exactly the same picture with the same content for R79.90. Head office says they looking into it on their site but i cannot get what was advertised for R64.90!!! even the zinger wings that comes with the meal wasnt advertised in the picture, it was 2 pieces of normal chicken even a rating of 0 / 10 is to much for them. absolutely disgusting!!!
