Sds Solutions — forcing me to pay the consultancy amount

Address: 500032

I have applied for this form filling job. They have given me a temporary id and password to check how the work progress. And after that they have given me the permanent login id and password. But i have not logged in to the permanent credentials to start the work as i get to know they are offering fake jobs and i have mentioned them in mail that i will not do this work as you are a fake company but still they are calling me and sending me mails everday forcing me to pay the amount. Before starting my work i have cleary mentioned them in mails to their representatives sai. [protected]@gmail.com and also to their customer care service that i will not accept this work.
Note : they dont have any website. I have talked with a guy with similar issue. They are targeting jobless and students. They will just send two pdf to everyone and then they say that we are having a bond.
