I would like to also confirm that you are not alone with your concern about cubits.com.
I’ve transferred a lot of money to their account and have not heard back from them.
I’ve reported this to the police and am waiting for a response back.
Bitcoin.com is just one domain name used to promote Bitcoin. Bitcoin.com is not an official website. Just like nobody owns the email technology, nobody owns the Bitcoin network.
As such, nobody can speak with authority in the name of Bitcoin.
