Just rang  ebay and they advise that dept of Fair trading is not considered Law enforcement is there an Australian Phone Number ?

 .....no way feedback can be removed sort it out with buyer .... I don't think this is  possible as we have already offered resolution through dept of fair trading.

Negative feedback hurts as we really have tried to fix this.I don't know what the buyer is after  as they did not truthfully relay events to dept of fair trading.

From my experience the highest expectations come from other sellers and also the worst outcomes if there is a problem.
