Employer demanding more money for resignation

4 years ago

I have submitted my immediate resignation due to wife's treatment and family issues. My original certificate are with my institution as per my appointment Oder, I am ready to pay three months salary but they are demanding my Singapore official trip money. In 2018 my institute sent me to Singapore for two weeks along with two students inten, myself and students are sponsored by an industry since these students are their sponsorship students . They stayed there for three months, my job is to set things right and return back . The institute debuted me as per company recommendation , they did not tell me any terms I did not sign any document, it was them you sent me, now I resigned and they are saying they will proceed the clearance formalities only when I pay sponsorship amount along with salary. In my current financial situation I can only pay the salary, because it was mentioned in my appointment Oder. Kindly need your advice
