Lied to me

Hi, I had recently purchased battlefield 4 for the ps3. And I only bought this game because they said I could upgrade to the ps4 version for an additional 10 dollars. I went in today and they said that Sony pulled out of that deal and I have to either trade the game which will only get me a third of what I payed or just keep it. I don't understand how a company can just lie about giving a discount and than revoking it.
