False advertising

I have a problem with Vodacome shake promotion, since it started in October 2019,when participating they send us codes that we have been put in a draw to win holidays, money and Audi A3 cars, I have not seen or heard about anyone being announced winning the draw for any of those prices mentioned, I feel that they giving us false advertising, I am not happy about this at all, it's also giving us false hope as customers. I am considering to consult this matter with ICASA
