Work From Home Online Job problem what to do

Company called K.D. Technology based out of Gujarat. They give work from home form filling jobs. I registered on 4 8 2018 for getting the work. They sent me a link to download an app where I have to upload my photo and signature. I told the executive that I am not comfortable uploading my photo in the app. She said that's okay you can just enter your signature and I did upload. No where in the telephone conversation she mentioned that my signature will be used as proof in a 20 Rs. stamp paper. I got the work and then i receive an agreement for my work where I have to fill 2200 forms and submit it within 20 days. I knew about the duration of work but I did not know that they will use my signature on a stamp paper. On 5 8 2018, I searched about the company and I see people have raised complaints on consumer complaint portal that K.D.Technology is a fraud company and they will find errors in the work so that they do not have to pay. I mailed them to cancel my work. Will this be a problem?
