Skyarise jobs - salary not credited

I have gone through copy typing project which posted in freelancer. At first, they asked to pay ***INR(deposit money). After I completed the work, I sent the work through the mail. Then they asked me to pay the tax amount otherwise we did not credit your salary amount(they did not mention this kind of payment to us before signing up for this work), so I paid the tax amount. After two days, they asked me to pay some amount to transfer the salary from an international bank(transaction fee), so I paid because they mentioned this the last payment process. Moreover, they asked me to pay IMT charges to transfer the salary between * to * hours, due to this reason I paid the charges. Now, they are again charging to credit my salary, but I did not trust them because they are the scam. Please help me because they have cheated us. help me to get my money back.
