Hi, I have tried several times today to start a car sales listing and it seems to jam on the page after I've entered the number plate.  Any hints would be appreciated. Cheers.

I recently bought some items which were listed on TradeMe. The listing kept on reducing in number available despite no apparent sales. To view the items I needed to contact the seller through the listed phone number. That's when I became aware that he probably sold nearly $10000-worth of product without paying any fees. Certainly my purchase from him skipped T/Me. The rest of us pay fees on our sales. How do I let TradeMe know he is doing this? Cheers.
