Have held about $AUD200 on there for a couple months and done nothing. I tried to buy $AUD200 of SNX today, my dashboard says I have $AUD210.30, but it says "You do not have enough AUD for this order to execute immediately." Same applies even if I try to buy $AUD100 worth. Chat says "a few hours" to respond.

Not impressed at all, seems more like a scam...
