Your story sounds very legit and we all know how some buyers can be very hard to deal with, but this comment....
I/we have spent too much time dealing with your sales.
makes me think this may not have been the first time.
You are defiantly not a scammer and this will end well for you I'm sure. If your not into frankens and modded pieces just buy some new watches till your back. Q is a pretty reasonable guy so for him to say that there is defiantly more to this but time will heal this situation. Just keep doing what your doing. I assumed something strange had happened with a sale with that under your name because all the posts I've seen you make have been normal forum stuff.
Most people don't think anything negative after they had heard you post so don't think it's that bad to have your name purple. At least it's not brown!
I guess your looking for a selling ban imposed on yourself. That can probably be arranged with the honor system and the sales mod team just incase. One chance will be all you get I guess. I am no mod here and am just making some opinionated, spitballed, mouth diarrhea here.
Best of luck to you in this.
