I submitted an on-line "At Market" order to sell my entire shareholding of XOM (exxon mobil corporation) shares approximately 48 hours ago.
The order was apparently accepted and showed that the price achieved was USD$69.43 each.

My chosen bank and currency for the "Electronic Wire" of the proceeds was my bank account here in Australia (in AUD).
This was nearly 48 hours ago and the website is still showing "Awaiting Settlement"
I have tried 4 times to contact the company using the secure on-line contact form on the website but to date have had nil response.
The company charges a fee for this supposedly fast International wire service and my details were submitted correctly some period of days prior to the actual sale.
The details when i filled them out asked for an IBAN (Australia does not use these) so i contacted them via the "Secure On-line" form to let them know the SWIFT code of my bank here in Australia.

Now i am facing an approximmate 13% loss of proceeds so far and still no sign of them releasing my sale proceeds or trying to answer any of my attempts to contact them.
The Chosen Currency was AUD and now the exchange rate is fast moving against my position that i have sold. I appreciate and accept a certain risk associated with exchange rates/fluctuations etc, but my order was placed during trading hours of the NYSE and 48 hours later there is still no sign of the "International Wire" being sent to my chosen account.

To whom should i address my complaint since i cannot get any response from this company (there is also a significant time zone shift between our locations so a call during their business hours is difficult).
In Australia we have a "Financial services Ombudsman" to whom i would direct such a complaint. However, i cannot seem to find the correct contact for the regulatory Authority whom goven these such "Shareholder and shareholding sales companies" in the region in which this company is listed.

Can anyone help to put me in direct contact with the correct regulatory authority whom control such businesses. I wish to register an official complaint and seek recompense for the huge financial loss that their actions (and lack of actions and contact) are causing me.
