Fraud | Unable to withdraw

I came across zipphy.com through an Instagram ad. I signed up, deposited $100, and was told I’d receive a 15% return per week. For the first three weeks, they did send profits to my Binance wallet, although withdrawals always took a long time to process. During that time, one of their agents kept messaging me on WhatsApp and calling me daily, pressuring me to invest more. I told him I’d wait a few months before deciding. Last week, the agent claimed my “1-month trial period” was ending and that I had to purchase their so-called AI system for $500 and add more capital in order to continue. I explained that I didn’t have the funds right now and would consider it after a month. In the meantime, I submitted a withdrawal request—but this time, they never processed it. Now the agent is ignoring my messages. I also noticed that during those first three weeks, every single trade they showed me was in profit, which is highly suspicious and strongly suggests a fraudulent system. Don't trade
