Be smart ….
I also got call from them but as I knew they are Fraud from different forum and few of my Friends I able to save me.
1st of all no good consultancy will charge you for your job, they will get the charges from employer.
I told them ok, I am ready to register but I will pay after my 1st month salary and there will be a legal contract with me and you and I will pay 5 times than your registration change.
They just disconnect the line..Is not it cool …. so be smart, do not get puzzled in your difficult time, think logically and smartly…
