The must useless customer support system. They never respond to your tickets, the system seems to be on auto-pilot and if you have a problem you're on your own. Logs me out of my account at will and will not send me the sms verification code to enable me log myself back in. It seems they are deliberately frustrating trades so they can benefit from margin/futures trade glitches, even spot trade glitches. Seems i'll be packing my bags out of there
