Has anyone had issues with ZercotTrades? my account was frozen

I was introduced to ZercotTrades by someone I met on Precious Metals Trading Platform App Latest Rankingsocial media. They helped me set up my account and promised I’d see a steady income from trading. At first, I made about $500 and was able to withdraw it. Encouraged by this, I deposited another $10,000. My account grew to $15,000, but when I tried to withdraw my funds, they said I needed to pay a "tax fee" of $3,000 before I could withdraw anything. I’m starting to think this is a scam. Has anyone experienced the same? What should I do to recover my funds?
