Fini Technology — fraudulent activities

Yesterday i received a message from fini technologies and then i saw a lucarative offer. They told me that it's a data entry job and that i will be paid a certain rs. 190 per page. They were willing to pay rs. 18500 for the first month and then rs. 28500 for the coming months if the job was done properly. They provided me a huge amount of workload and which is essentially senseless. Hence, i got suspicious and had realized i got into a contract too quickly and they had used the loophole in order to extort money from me. They said in case i do not meet the 90-100% criteria, they will terminate the contract and take rs. 9500 as fees. Initially they even took 300 rupees as service charges.
Now i see from the numerous complaints that this is all a fraud and no one will ever achieve that kind of accuracy.
So i request that this issue be resolved as soon as possible.
Also they had taken my personal details and they might be misused.
So please help me terminate this contract as being a student, i cannot afford the loss.
