Quicker — Payment not received

Address:

560055

I am 16 years old student. I applied for a data entry job through quicker jobs.
I have paid rs.1350 through paytm for registration. They employed me and sent me the work pdf.
I completed the job and typed according to the information which i had provided earlier. Now they are not giving me my salary and asking me to pay rs.4000 more as a gst tax for 11 months. I asked them why should i pay tax and they replied that they will return those money to me included in my salary. I tried several times to conatact them but their phone no. Is switched off.
I am giving you a video between me the person who hired me.
