it's scam don't add more money to do more task .

This website says that if you invest $20 with them, you will get $10 per day for 30 days. I also tried it. On the first day, I received the money, and in the following days, I also received it, but then they didn't allow me to withdraw my funds. When I contacted customer service, they said I could withdraw only after 5 days. So I waited for 5 days. Every day, I completed the tasks they asked me to do and accumulated $10. When it came time to withdraw, they didn't give me the money. They made me do additional tasks and asked me to add more money. I don't know what to do now. Please help me. I have $164.5. How can I get it back?
