Blockchain.com Blocked My Funds and Asked for Additional Deposit to Release Money

I recently built a wallet account and, following a friend's recommendation added Smart Financial and linked it to the Fun address. My acquaintance informed me that I would receive a daily return and that I could withdraw the funds whenever I wished. However, I discovered that money had been removed from my wallet without my permission, which shocked me. When I contacted Smart Financial, they advised me that I needed to deposit more money to get the money that had been stopped. This is quite unnerving, and I'm not sure what I should do next to fix the situation. I'm asking for advice or assistance in determining how to safely get my money back.
