Lost a load of crypto after trying to 'refund' something from Caroline June Palm Beach, scam or just dodgy?

Ok so, I feel like such an idiot right now. I ordered some stuff from "Caroline June Palm Beach" a few weeks ago, online. The clothes arrived, but they were NOT what was advertised, like, super cheap quality, wrong sizes. Anyway, I tried to process a return/refund. Their online portal seemed dodgy so I emailed their 'support'. They replied saying they only process refunds via crypto to avoid international bank fees, which already raised a flag for me. But I was desperate to get my money back. They sent me a link to what looked like a crypto payment gateway, saying I had to "verify" my wallet by sending a small amount of ETH, which would then be refunded along with my purchase price. So, i, being dumb, followed the instructions and sent about 0.5 ETH from my Trust Wallet. The transaction went through, and then... nothing. No refund, no communication, their website is now down. I've been blocked from their social media too. Is there any way to track this? Or is my ETH just gone forever? I feel sick to my stomach.
