The page did exist in 2011 and doesn't exist now. This is already mentioned by HCP.

It is not safe to put any fund in a custodial wallet even for a second let a alone 10 years.
As mentioned multiple times, your fund is gone and there is no way to receive that. Forget that 56 dollar.

If you are still interested in bitcoin, learn the lesson and from now, use a secure non-custodial wallet. In this way, you will be the real owner of your fund and will never experience such issues.
