USSC Group — cheating many people in the name of form filling

They charged 3000rs saying that we have to fill 2000 forms i 15days and after paying the amount and taking the work they called me as 3rd party saying that they are from JS typing center associated with USSC group and can do the work at 1/4th rate and for that they asked me upfront payment again (i have all mail and msg proofs for the same) and when i rang up the branch office and head office everyone agreed that that company is associated with them and i can outsource the work if i need wherein i denied it and filled them on my own and submitted before the time but now they simply left a msg saying that the qc got rejected and to my shock the forms that i submitted are quite different from the ones they are showing now (i even stored the screenshots of the forms i submitted). Now the delhi branch head mr. Mayank is agreeing the fraud where in mrRaju from the main branch is calling and speaking all non-sense and threatening me. So whomever have faced this can join together to file an FIR against them.
