Last person that came here flaming Outlaw lost big. Outlaw responded to him here.
Thing is, airing Dirty Laundry out in public is a very quick way to make brick wall out of a mistake. Quite honestly, the fact you never provided them the serial number in the first place is looking like the most simple root cause.
If you badmouthed them at all in conversation or email, they will lock the case: this happened to the other guy! Outlaw has a zero tolerance policy for abusive communication.
So, NO, what you are doing is not productive.
Believe me, if something were going south with any Audio Company that has a pretty good reputation, we do want to know. And Outlaw has been a good company for many of us here.
You need to stop this, focus on working through the problem with them, and move on. Short of that, if you do stir the pot, you won't get anything from them but a Cease and Desist order.
