Dear oh dear oh dear...tut tut tut

Listen guys, you know as well as anybody, that dealers like that do not play by the rules...therefore, if it doesn't backfire on you then, it certainly will in the future.
He'll be hiding round a corner with a baseball bat (or worse), waiting for you. He'll get you back when you least expect it.

The best way to deal with people like this, is to vote with your feet and spread the word. Tell everyone you know that he is a dodgy herbert that rips people off.
Tell your new dealer about him, and they can spread the word too (they'll be glad of the extra clientel, geddit?).
The pay-back will be longer in coming, true, but at least your hands will be clean, right?
And hey, if you told your new dealer about it, maybe you can wangle some special deals from him, like as return for getting him some new customers, init?

You gotta think, guys!
When I found out about my best mate shagging my wife, the first thing I wanted to do was to find the bloke, and feed him his head - but, if I did that, I would be the biggest loser; wouldv'e lost my kids, got banged up in jail, and allsorts of boring shit.
Better that I just spread the word, wait for him to shag someone elses missus, maybe the next bloke won't be so thoughtful, know what I mean?
When the payback comes, I'll be able to stand on the sidelines and rub my clean hands together in glee

Your ex dealer sounds like a complete asshole, dude...maybe your payback won't be too long in coming

It's what I would do
