Work Planet - Not paying compensation after completion of the online work assigned to me

After checking ads for home based work in naukri , I called a company called Work Planet which is based behind IBIS hotel in Bommanhalli. The person who contacted me by the name Sapna said that there was no registration fees and I had to visit their office for some demo.
I went to their office on March **rd and after the demo a person by the name Aradhya said I had to pay ****. We were totally confused and she said that I had to deliver the ***pages project within **days with **% accuracy. She also mentioned that I needed to spend just * hours perday. Assuming that the percentage calculation was with respect to the total number of words in the project we accepted it. I paid that **** and they were supposed to pay **,*** after the project was completed.
I started my first project on April *st during the lockdown. Their saying of * hrs was completely wrong, as I had to type a novel which was in jpeg format.
I had to type atleast ** pages per day to complete within the stipulated time and each jpeg file has ** lines with approximately ** words per line. This took me almost *hr per jpeg file. Inspite of spending **hrs per day and sending them the project after taking permission for *days extra, they send me an error report where they calculate each spelling mistake as *.*%. My project has just ** spelling mistakes and they send me an error report that I have **.*% errors. Surprisingly, this is calculated as ****.*% . Hence they say that I cannot get the payment as it is not **%.
Percentage means out of ***. So we presumed that *.*% means * spelling mistake for*** words. I had typed *lakh twenty thousand words using my hardware and my manpower. All this is just ignored and they continue to use my project without paying and taking Rs **** from me.

They tell us to sign a contract which is not discussed before making the payment and they tell us to say that we accept the contract which is completely one sided for their benefit.
