Execuland, a white-collar recruitment consultancy with offices on the 41st floor of Emirates Towers, was also found to be advertising jobs despite not being registered as a recruitment agency.
Nobody from the company showed up for work on Sunday, according to a receptionist outside the firm's office, and telephone calls were directed to voice mail.
UAE recruiters are only allowed to charge employers for their services.
Previously only a problem for blue-collar workers in sectors like construction, the economic slowdown has seen illegal recruitment fees spread to all parts of the market as a wave of redundancies in Gulf states created a surplus of job candidates.
Article 18 of the UAE Labour Law states that: "no licensed employment agent or labour supplier shall demand or accept from any worker...any commission or material reward in return for employment".
In a statement sent earlier to Arabian Business, Humaid bin Deemas, the acting director general of MoL, said that jobseekers asked for fees should submit a complaint supported by evidence to any of the ministry's customer offices.
The managing director of Execuland did not immediately respond to e-mails.
