incorrect chips size given

so i wen to Steers Jabulani mall , order the king steer burger Meals come with med chips. Combos come with med chips & a sugar free buddy.Meals come with med chips. Combos come with med chips & a sugar free buddy.

i was then given small chips and when i asked the lady that was helping she advised that that's the small chips are given with the meal combo , i was very upset as the other franchises give you what you pay for
