Spring is a fraud platform. Unable to withdraw

I was cheated of 4,000 euros and asked me to pay 20% tax to withdraw money. I paid it, and then another deposit was required, but I couldn’t withdraw it. The regulator is forged by myself. There is still a lot of money in my account. I have never withdrawn any money. Don't be deceived. Even the complaint mailbox is fake. Hope the relevant departments will solve it as soon as possible
