Impossible to contact Metamask support

Around 2 weeks ago, I transferred 3.2 ETH from my Binance account to my new Metamask wallet but as I am a beginner it didn’t go well, got confused with Binance Smart Chain. Finally got help with the community (thanks Luigi), where finally the funds appeared on my Eth account. But 10 days ago, I got SCAMMED by metamask@securetechsupport. He offered to help and asked me for my seed phrase which I was stupid enough to give out.
Transaction ID was the following :
Tried to contact support at Binance and at Metamask for the last 10 days, only dealing with bots, no help whatsoever. Any advice besides I made a stupid and costly mistake ?
Thanks a million …
