You're right! My neighbor didn't want too much trouble from this.
When we were talking, I did ask my neighbor why didn't he just tell him the exact amount he wants and that's the most he's willing to pay. Too bad for whatever the brothers sliced up.
My neighbor said he just want to avoid trouble and at that point when he was "hit" by the scam, he was literally shocked to the point he couldn't think straight. Which is also why I am sharing his story here in the hope that by spreading such information around, we can "counter" these unethical sellers when they strike! For me, at least now I have a "script" in mind should they come knocking on my door the next time - "Get lost!"
