Does anyone know how I can reach Julien (Jooc), he has sold me a FAULTY MOBILE, and agreed to return it then he didn't accept any PM so I can't reach him

please do not buy anything from him, as so far he has proven to be dishonest and evasive, and if u know of any way I can get to him it will be appreciated

His Real Name Julian
His Picture is in http://members.lycos.co.uk/joo1s/gallery.html

Thanks in advance
