Is it obligatory to pay the agreed-upon fees to the mediation office two years after finding the job, especially given that the office did not make a direct effort in the current coordination?

It appears that the work for which the office is entitled to a fee is directing the applicant to the two jobs, and he has the option to accept them. If the applicant pays the office the agreed-upon fee and wishes to transfer to the second job, there is no impediment, and he is only obligated to the initial fee. As for brokerage with a portion of the salary, its permissibility is debated among scholars, and the preponderant opinion is that it is not permissible.
