Well, that is what lying assholes do. I do like that his argument boils down to "No, I was lying back when there was nothing to gain from lying, this time when I have something to gain from lying I'm telling the truth!" with a side of "Going out of your way to help me reclaim my stuff is not 'help'!"

It's like he's trying to make himself look like an ungrateful and inveterate liar. (But really, it's just the mask slipping.)
