stable overseas jobs - cheated on telling jobs about foreign country

Hoffman scott contacted with me through linkedin and later through whatsapp we chatted during at that time he asked me to pay ***** for first and later after getting job i need to pay ***** for singapore. I paid **k but later he said there was a job awaiting for me and they are asking for IELTS qualified students so he asked me to pay **k but after some negotiaion i gave him **k later on he again messaged to pay **k for interview process if not i will fail. but later on i asked him about refund and exam application but he was failed in giving it. Even though i also said him that i cant afford furthermore he told me to borrow from others and have to pay must and should.
