as above,
im a financial banking ombudsman. not advice, but what i would do
call my bank and lodge a dispute on the funds as "un received goods"
They may decline the matter due to authorising the transfer through internet banking.
If they decline it, make an ombudsman threat. as it will cost the bank over $680 if you simply lodge one.
i know it suck that they may get away with it, but doesnt mean you should be down the deal.
