I lost INR 195,000 in a day, and now also they are asking me to pay more INR 400,000 to get my all money.

Earlier they given me small task to do with Google Review and then they paid me amount for those tasks. then they asked me to opt out the pre-paid task and then they keep asking me money to release my base amount. 

Please help me, I have borrowed money from my friends and I have no way to return that.
