Sorry Robbo..
Disagree totally.. I am a UK power seller and i have a feedback rating of 100%.. and always leave any disputes up to paypal to sort out.. Indecent seller or shady characters have nothing to do with it..
You would not back down if you knew you were right.. So why do it over the internet.. ???
Just be to nice..???.. i dont think so... Its all business.. if you cant handle the heat.. stay away from the fire..
