Misleading adverti*****t and Rude service

Good day,

Last weekend, my kids and I just needed fast food and we decided on KCF. We went to Maponya Mall to get the R99 special which includes 6pieces of chicken, chips and a 2l coke. They unfortunately said they do not have Coke and we could not have the special. We drove to bara Mall (by the hell garage) and Molalo (Manager) said they only have the special on Tuesdays. We drove to the KFC opposite South Gate by the Engen garage and they also said they do not have the Coke so we can not order the special. We confirm the special with the cashier and she said yes it runs everyday until further notice and we told her that, her colleagues at another branch said "only on Tuesdays" and she blatantly confirmed that its everyday. We ended up ordering KFC street wise 3x2.... We drove back to the KFC at BARA by the (shell garage) and asked the manager Mlalo, "why is he lying to us about the special because his colleagues said it runs everyday." He said, "No it doesnt not" and i said "okay I will have to report this" and he said rudely "go ahead and tell the person you are complaining to that my name is Mlalo" and he walked AWAY. We were so frustrated about this lack of training or incompetency that we experienced in the South (KFC's) especially with Mlalo. We are paying for this food, its not like we are getting it for free or using a voucher. Is the special available or not because it is advertised but when we go to the KFC stores we get excuses and rudeness for the stuff. Please assist, Thank you
