payment problems

So the last trading day of AOE is 30th July! payment is 23rd August what AOE may not know is that I have shares as security as part of a margin loan so I assume CommSec will not lend on AOE any more. So its possible many people in my situation COULD have a margin call and what happens if selling the shares will effect your LVR and brokers sell off other shares to bring it back up.The point I'm making is the days between payment is far to long I NEED MY MONEY on the 30th!!

ps can CommSec hold my AOE shares and not release them!
