They locked my account with no explanation for over 2 months now. Customer support has been extremely slow to respond, and they said they would hold a security interview in 1-2 business days to have my account unlocked... this was 5 weeks ago, with no response since. Worst support I've ever experienced, I honestly don't know how this is legal. If they weren't IPO'ing I would've assumed they were insolvent.
