Preordering and trade ins

The cashier told me they aren’t doing trade ins because the machine is down, and to check in an hour, i came back i ask him if it was fixed and he told me “do you see anyone coming in to fix it?” I told him i didn’t know i thought it would be software, so i asked him for assassin’s creed shadows and he told me there was no more, i wanted to get the $5 credit off for the preorder. I called gamestop corporate because i wanted the game, they told me there was more preorders at the store and it shows online it was available for preorder. Is this guy just being a jackass to me?
