Thinkonik — data entry job

This is a fraud company. On april 1, 2020 they called me and told me about their data entry offer and they told me to deposit 500 rs for the software or to give the data files, so i deposited the amount. After that i was asked to log into their website, thinkonik.com. And to select the plan. The plans were 2500, 3500, 4500. I immediately called the person who offered me about the job and told her about plans, but she told to select 2500 rs plan that the company will pay 2000 on behalf of me. I selected the plan and logged into the main page and downloaded the data file (15 files), finished those in 4 days and uploaded in their website page only. After that i mailed her for payment she told it takes 2 days for the payment after the upload, after 2 days i did not get my payment, again i asked her (Swetha) what about the payment, this time she gave me the number of another person (Sindhu) telling she is in charge of payment. Ok, now i called her she told me to pay remaining 2000 then only the payment will release and i told her when i have already finished my files and uploaded the files for you people why i should pay instead you should pay for my work, ok then i told them withhold the 2000 rs for the job what i have done and pay the remaining but no respond after that till now.
