A worker at the Ratanakkiri provincial office of mobile-phone operator Metphone has filed a complaint with local rights group Licadho after he was allegedly told to pay US$2,000 for a company car that was damaged in a traffic accident. Koeung Phea, 25, said Monday that employees of the Vietnamese company Viettel, which owns the Metphone brand, had presented him with Vietnamese-language documents that he refused to sign. Nguyeng Duy Tho, the managing director of Viettel, could not be reached for comment Monday.
