Scammed on OpenSea via MetaMask—Bought NFT Under False Promises

Dear OpenSea, five days ago, I purchased an NFT through MetaMask after being directed by someone I trusted. It turns out they most likely tricked me into buying their own NFT. After the transaction, they deleted their Instagram account and deactivated their WhatsApp number, making it impossible for me to contact them.

This person promised that the NFT’s value would increase 5x within a week and that it would definitely sell. Now, I am left with an NFT that I cannot liquidate, and I feel completely scammed.

OpenSea, I need your assistance in resolving this issue. How can I convert this NFT into cash, or is there any action I can take against this fraudulent seller? I expect a prompt response!
