It sure is simple - there hasn't been any receipt provided, he refuses to answer that other bloke's main questions, active members have claimed wrong-doings, and no doubt there are plenty of others who haven't spotted this thread who have had similar problems
So here comes the easy part - given you're a mod, instead of referring people to the police, do every other SAU member on here a favour and let them know this guy has numerous complaints against him from all over Australia - that bad traders list for example hasn't been touched since 2007?
I would never have read this thread had it not been for the fact I was interested why a new turbo would attract 6 pages of discussion, otherwise I would've happily dealt with this chump and, from the look of it given I can't meet in person, lost my money.
More action is required so other SAU members don't fall victim IMHO.
