False Adverti*****t

I ordered a bucket for 1 with free stoney drink online and collected at KFC Beyers Park, 135 North Rand road Boksburg on the 01/12/2020. I was not given the free Stoney drink but was told that the promotion has ended. I regard this as false adverti*****t as my invoice stated the free Stoney drink. What I ordered and paid for is not what I received. When I asked the person who served me why the free Stoney drink is on the menu, he told me that he is not responsible for what goes on the menu. KFC is guilty of False advertising
