Just to be clear, if what the OP laid out is correct then yes he was the wronged party.
However RWI has a policy on how to deal with these situations and they also have a very strong policy against PP disputes...why?
Because it is the people who use PP as a first option that are destroying our hobby, most dealers who have years of excellent reviews cannot use PP because of the selfish, unrealistic or instant gratification people who, by starting PP disputes, have seen their accounts closed.
Even this forum which has been a safe haven for so many has suffered many problems because of PP issues.
All the RWI team asked was to be given time to sort the issue their way, no one would have begrudged the OP starting a dispute if time was running out and there was no resolution but he states clearly that he opened the dispute within days.
The other party may very well be trying to scam...but then he may also have simply gone on a business trip too.
As I said before all these boards are privately owned, they have their own rules and if you wish to be a part of the community then you are expected to follow those rules, your preferred business practices simply do not count.
