They take our valuable time and work for their own Benifit. Then when we are close to achieve our target they do a fake review saying that you did mistakes even though there is none. They ask you to pay amount of Rs4000 and if you don't they threat you that they'll take legal actions and make you pay upto Rs25k.
They even took aadhar and PAN details before starting the work for the sake of I'd before starting the work and may use it in a wrong way.

Where else should I complain about it?
