edmiston yatch hotel recruitment

after first reply from so called company (falsely representing EdmistonYatch Hotel)with regards to my question on company profile... i was lil doubtful as they seem to divert their answers and my attention on needing staff urgently. to my ignorance n unbelievable stupidity despite being cautious most of the time i send them my passport scanned documentsn(B.N.O). Am living in H.K. Now am scared about what they can do with that n how could this be stopped??? please help me... am also thinking of reporting it to british consulate in H.K. ??? Thanx
