Until now the only evidence he has posted is that he don't want to verify his account because he "don't want to provide my personal data to every third-rate exchange"
He is sending support tickets with another email address (probably fake) so of course he will not get any reply back from support. "Tryied with another mail address - the support request passed through! lol"
He shouldn't have to verify his account in order to get his coins out of it. If anything they should just not allow him to trade. But with-holding coins after springing KYC on somebody is pretty sketchy.
Plus there's dozens of other user complaints for similar issues on Twitter, Reddit, and here. And then one guy who submitted KYC and still can't access his account... This exchange seems to be scamming their customers. Until one of its employees can explain the rationale behind with-holding coins after asking for KYC, I'm going to assume its a scam exchange. As should everybody.
