One day i received a call for capcha work from home based i thought i will be able to do that and didn't concern it from anyone. She asked for a id card photo.
Then i was not to do because i was sick. Then one day was left and she called me and said we have automation of this software the capcha will be filled easily and i paid 2500 to her. But the capcha still remains to fill. One day i receive a call and she said u have to pay 5100 as per the agreement coz u r not able to fill 10000 capchas.
I mean the one i fill that they took and the money also i got so pissed off from the calls still i paid coz i didn't want any legal action. She send me some notice n all.
I forgot what is agreement, it is void.
And without your concern, sign and without notifying you, you won't be able to do so.

Then i received a call yesterday i called my mom n tell her the story, she said tell him to send the notice. We will see..
I concern my boyfrnd n he said its fake n all.
Don't send money n all.
I felt like i am a educated "gawar"
Now tell me what should i do?
If they will send some fake notice to my home.
