Honestly, from your writing it is difficult to understand how the chronology of this scam was carried out. Don't know until to what point you sent the crypto, or whether the scammers sent the money first, I don't know. Until when your case was made public, I just found out that a phone number is needed in Binance p2p transactions just for communication. Afaik, off-platform conversations don't count.

I think binance support feels the same way so your case is poorly resolved.
