I Net Solution — torturing for payment for work which I already did

Address:

102 K V Nagar, Veer Azad Marg, Latur, Maharashtra, Latur, Maharashtra

Dear sir,

I have took work with i net solutions last year and completed work. They told i am not achieved target, so need to pay 10, 000 as utility charges and i paid charges and got noc.

Two months back again i received mail from legal department of i net solution and asked me to pay for 11 month agreement fees, i told them already paid, now they are saying if you are not paid fees we will file the case in delhi court.
Yesterday again they called and asked me to pay immediately money of 16000 to close the agreement, i borrowed and paid the money, now they are asking again need to pay rs.9500 to signature cancellation charges, if i am not paid then i need to appear to court and pay the charges or face the consequences.

How to deal the case, the mail id i received is "[protected]@gmail.com".

Now i am totally sick and unable to do any work, due to this mental torture, so to whom i need to approach take action against the legal team (They are real advocates / duplicate).

Regards
