Well, in lieu of this guy defending himself (and you always should hear both sides of a story), here are my observations:

He's either a crook or a pathological liar.

A pathological liar cannot tell the difference between truth and fiction.

That means they might be telling you something false, but at the time they're telling it, they believe it to be true.

Of course, it's possible that this person deliberately lied because he's observed how so many people and corporations lie and usually get away with it to their advantage.

I can almost guarantee that if you confronted him, he would either express great suprise, or at least complete denial of any wrong doing.

Here in the U.S. we would take somebody like that to small claims court.
