Bad stuff is inevitable, but what is important is when both parties try to make amends. There have been instances where I have personally seen the willingness of both parties to resolve the issue, and it ultimately has.
This thread was posted 4 days ago and there is still no clarification or explanation from the accused. I do not know this person and am thus no one to pass judgement or contact him, but those who have tried to do what I would have relate instances of abnormal and unreasonable behavior. Sadly, the willingness to resolve this is missing, and due to that, I doubt there will be much resolution here no matter how many posts are made.
My humble suggestion is to look on the positivity here: OP had the wisdom to not fall for a bad deal, and there was no instance of looting/cheating.
More importantly, a person from our midst who was not fit to be part of this family was revealed, and his true colors are now public knowledge and a future warning to everyone.
I suggest we move on from this unpleasant episode, content that old misunderstandings can now be understood and resolved with this latest revelation, happy that someone unfit to be at PW is gone and that the OP did not get cheated out of his hard earned money.
Peace.
Oh, and good luck to the OP with his audio setup!
