Commsec did the same thing to me after I phoned them Re my account.
They asked me if I was calling from overseas, then would not allow me to buy, only sell.
I transferred all my holdings to Westpac share trading.
My local 7/11 on Thrappaya Rd Pattaya ceased selling alcohol at 12am today.
Tried to explain that the ban doesn't start till midnight tonight but to no avail.
Just went down the road to Foodmart and bought it there instead
