False advertising

Good day, After buying a box of oreo cookies covered in chocolates in Hoedspruit to enjoy while my trail hair is done for my wedding i saw that the one packed inside the box only had 1 cookie in instead of 2 as shown on the packed which i decided to take a video of at home ... After paying quite a lot for the box i was very disapointed to find less than what i was supposed to... feeling ripped of... Cadbury is more than welcome to ask for the video that i have taken
