Let's face it, you have been incredibly naive here. Best not to dwell on it too much though as, unfortunately, with the best will in the world, you won't get be getting your money back (sorry to be blunt but that's the way it obviously seems). You will just have to put it down to experience and move on I'm afraid.
I suspect when we first start punting we all fall for some trick or other. I, for instance, fell for the classic “bait and switch”..instead of walking paid top money for a WG I didn’t really fancy. Just daft.
But deep down I think best policy is to just take these reverses “on the chin”. Don’t make same mistake next time, but don’t get involved in some epic campaign to get even.
Too many things can go wrong...the reality is so different to many of the tales we see recounted from time to time. “I knocked out the first pimp with an uppercut to jaw..”. Yea...maybe, or maybe not.
And reality is...as one of my punting mentors explained years ago: “if you’re worried about spunking away large amounts of money, find another hobby”.
