Website: www.infinitysol.in and www.onlineform-filling.com

Hello i have started working for infinity solution fron 15 june 2016 and i was told that i have to complete 1500 forms in 20 days . My deadline was 5 july 2017, but on 3 july 2017 i received a email from them saying that i have violated a term of contract and now i have to pay them 5100. As a fine but when i asked them the reason nobody replied and received my call. Now today they have sent me a email again that if i not pay them 5100 rs that will take some legal actions on me. I had 2 days of work remaining and 450 forms remaining. So thay have cancelled my contract just 2 days before without any proper reason. Kindly help me sir
