Could you please clarify what happened, and what site it is about? I ask you this to protect others who may become victims of the same scammer and that we can report that site to Google as phisning.

If I got it right from the post, your got your Ledger only recently, and you only lost that altcoin mentioned in tweet. But I see it is a more substantial amount, so I'm sorry for your loss. I visited your web site and see that you have various skills, maybe you can offer some of them in the forum Marketplace.

In the future, if you need support for your hardware wallet -> Hardware wallets.
