unable to withdraw

have a live and demo account with Onada. I recently tried to make a withdrawal of $300. On Onada's site the withdrawal was shown by deposits I had previously made and showed that the withdrawal was completed. I asked customer service why it wasn't shown as a single withdrawal (transaction) and why did you show the withdrawal with deposit amounts I had made. She really did not have a valid answer. All she really said was that's the way they "do it". The funds have not shown up in my account and
