Udcon Enterprises — help

I recently joined this company for a home based handwriting job. I finished writing and sent the book too. When it was time for the payment they marked lots of errors in the project that i have written. They did not even give proper training and yet they expect us to write like being typed by a computer.
Please help me

I Paid 1800 for this company. They sent me the materials. After receiving it they didnt provide proper training. They told me to write in capital letters. I finished writing and submit through whtapp and courier. After that i sent so many messages to hr ayushi, she only not responding in a good manner. Now at the time of payment she told me that there is lot of mistakes in project and couldnt pay the amount. They can pay only 300 rs or have to write second project. They should pay 18000 to me.
