Thievery !! @ Large

I saw a Promotion get 1 meal and then the other free ... no promo code was sent to my email or on the adverti*****t which was on Uber Eats and then I called. Called Burger King Tableview and the nice lady says that when they get the order it shows 2 meals and that’s what they do. I then ordered from Sandown as it’s closer to me and got 1 meal. Just 1. So I need to know where is the rest as advertised ? Full refund as in yesterday. If it means I have to log a complaint everyday ... trust me I will. And take it further.
