Data Entry Jobs — payment delay

I have paid the document charges, agreement charges etc... And they said you will receive the salary... Within 5 days... Then they said you have pay code update charges then gst...
I have not even received the payment.
I have waited at least they will pay
.. They are not responding properly.. They are asking to pay gst amount and then payment will be initiated.. If i ask any query.. They are saying just to wait...
