1000 FALSE ADVERT

I saw an advert where Miways said if they cant beat your deal they will pay you R1000 I took them up on the challenge and well as expected they couldn't beat my deal, after the advisor offered me alternative deals they still weren't able to beat my deal...they say they want to compare apples with apples but when it comes to the actual part of sending the money or taking the offer further I get told that only a selected few people were chosen for this and entered into the system to get it... what kind of false advertising is this, I thought they would be ethical in how they run their business but I guess I was wrong...Even if Miway were to offer me better in future I would never consider as if this is how you do dealings at sales stage what will happen at claims stage
