Curry Up - False advertising and ridiculously small portions

This business has been using false advertising on the Uber Eats app for ages. They claim if you buy one particular meal (Butter Curry) you'll get one free. This is not the case. If you see their Google reviews it's been going on for a long time and they've made no effort to rectify it. In addition, their portions are dismally small to say the least. One of the biggest rip-offs in Johannesburg.
