Why did I deposit that amount and verify the identity even though the site does not look real? When you verify identity, this is a reliable website, not just a routine procedure.
I fear that you lost your currencies in addition to losing your identity, which may have been sold so be careful with these sites and do not do them only with a reliable site.
Though i have never used the exchange, i believe it is real. It's an exchange of Blockchain.com(if you visit Blockchain.com, you can easily get the exchange URL of their exchange from the website)
So OP should not lose hope. There could be a reason his funds are locked up. Only the support can help him as of now.
