We had all this on another Forum. Some kid sold loads off gear to various people on the forum. After getting all the money but only sending some of the gear to a couple of the buyers, he just ignored all attempts at contact and this lasted months.
What eventually swung it was that a forum member found his mother on facebook and posted it up on the forum, she turned out be as pissed of with her son as the peeps that hadn't got their gear, she must have give him a slap because he showed up with some lame excuse and slowly it all got resolved.
Conclusion was. Some young lad got himself into a mess and didn't know what to do, not really dishonest more ignorant but in the end everyone got their gear or money back.
Luke, i hope you get a result. If its a kid try and get hold of the parents.
