50/50 special a lie

Their 50/50 birthday special it a lie. According to the adverti*****ts, app orders are limited to 5 per customer and in-store orders to 2. Ordered successfully on app, when I went for collection at KFC Naboomspruit (since they don't have delivery option) they refused to give me the order saying they're limited to 2. Logged a complaint with their head office and they never attended to it.... I hate false advertising with passion
