Hi all thanks for all the support and advice. In the end trademe contacted me pretty quickly and told me it was infact a scam and the sellers profile has been removed. Because of already being suspicious about it I hadn't given any money etc so it was all fine in the end. Also after a few days the unfair negative feedback was removed so phew! There wasn't any fine print in the ad that super quick feedback was required etc so thats why I became weirded out by this aggro behaviour by the seller haha. Thanks again everyone!!!!
