Someone pinged me on WhatsApp mentioning part time job, at first I denied to take this but she kept pinging me claiming that they are are not fraud, i don't know how i agreed with her then she sent me a link of Telegram and said to give five star on Google for Trustpilot product in return i will get ₹*** and i did so by following her and they sent me ₹***. Again she said to complete another for ₹**** and i did that too. Again she said to complete bigger task for ₹**** and i did but this time they sent half amount and said to pay ₹**** to merchant claiming i will get double of my amount that is ₹ ****.
And gave me a bigger task to complete when I did the task they said i made a mistake that is why merchant hold my amount. Again they said to pay ₹***** and assured me i will get ₹******, i denied but they forced to earn more and i sent, then they sent me half of it to build my trust and said to pay ₹****** claiming that I will recieve my whole amount in one time, and I sent ₹****** then they freezed my U-coin Digital trading wallet . My total funds is ₹****** including my profit.. now they are saying to pay ₹****** again to unfreeze my wallet account. Now I am helpless, please help me to unfreeze my wallet account.
