And what happens if the funds were deposited from an exchange? I am not privy to this information, only the OP can say. Nonetheless, the 2fa and email confirmation is more than enough.
OP can confirm it.
However if the theory of sending back the btc where it came from works then OP just needs to confirm which address he want the 330
BTC back. Send that BTC back there.
PS: Anyone who deposit that much money should use their own wallet not an exchange or third-party wallet which private key is not his own.
update:
I will wait what will Ronnie/Cloudbet will say. Then ill do it. I will wait for his reply. My documents, the 2FA the email verification I guess is enough. But if they need something more, please tell me and tell me ASAP. Thank you
Awesome.
