Did you reply asking what is wrong with the information you provided? Might be best asking them what was incorrect with what you sent them.
Unfortunately thats what a majority of people do. Start a scam accusation thread before following up with the site or service.
@Op, mail them back and if you get this resolved, please update this thread to avoid public confusion. I haven't had a problem with KYC verification on their site.
Sure i will update this thread if issue get resolved.
