Grayscale Exchange Futures (future667.com) — did anyone else get hit by this one?

I really need some advice. I met someone 'online' a few months ago, they seemed lovely, we talked for ages... then they started talking about crypto, this platform called Grayscale Exchange Futures, future667.com. They kept showing me screenshots of amazing returns, telling me it was a special 'group' they were in and they could get me in too. I started with a small amount, then a bit more, and then they pressured me to put in a significant chunk of my savings. Now, suddenly, I can't withdraw anything. The 'customer service' is saying I need to pay some huge tax fee to release my funds, which I know is a lie. I'm in bits, honestly. I've lost about 12k euros. I'm based in Galway. What do I even do? Who do I report to in Ireland or internationally? My heart hurts so much, not just for the money, but for the betrayal. Any help would be so appreciated.
