On August 24, someone dumped a bunch of MINT in my account, and bought a bunch of XC. My account had about $365 worth of coin now it reads about $5. I emailed support but the emails seem to not have reached them since I got a message from the mailer Daemon that they failed to get sent to their support address.
I don't see bter is got a hack but maybe you need to wait for several days and I think their just having a problem with their system but maybe better for you to try again sending a message for their support for a twice.
