Electron — Threatening phone calls

I have got a massage on my whatsapp number about a form filling job work from home. And i joined then they gave me the password and username and they signede with an agreement of electron that's their company name. After completing my wrk i submitted it and they said me that your wrk is not 90% accuracy so i have to pay the penalty amount 9200 so i paid after that some advocates call me that they will claim me and threatened me to pay more money and i paid them more money as they said. Then again they call me that you should pay 45000 for your digital signature that i didn't paied. And they keep calling me from different numbers in 2019 to 2020 and suddenly stopped the calls in covid time and now 2023 they are still calling and threatening me to pay more money so they can close your file otherwise they take leagal action an all that please help me. Is this real Or fake??
