He's stupid though.
The good ones try to extort and when they don't get their way they move on to the next victim. Leaving negatives/neutrals/low DSR's is just like leaving a paper trail.
If you're not going to give into him then you certainly aren't if he leaves a neg/neutral (unless he says he'll remove it for the refund.... but that is even more obvious extortion).
At first, I was thinking of giving him the refund...Because a partial would be like $15...which is nothing in the grand scheme of things.
Then I thought, I'd offer to have him send it back for a full refund.
But then I figured..F*ck that. I'm going to teach him something about Karma.
I'm going to go to the mattresses.
So, now I'm going to wait till the neg is expunged and the case closed.
Then I'm going to block him.
And then I'll teach him a lesson.
