Managed Payments Nightmare

Hi All - eBay stopped our payouts on 18th April as we needed to apparently supply more information - CS told me this was because the DOB of the business stakeholder did not match what was on the drivers licence (all of a sudden) - We updated this several times but kept getting the message. Contacted many people in MP and was told on Friday by chat that they have all the info they need and it is all verified so they will raise a ticket with IT to get it fixed and release payments - Saturday we made no sales (it's an anchor store - typically we sell 20-50 product each day) Sunday no sales - back onto chat - this time I'm told that they can see the IT ticket but it hasn't been actioned yet and that their system could not verify my ABN (been live on MP for almost 2 months at this stage with no issues) - Explained there was only a field in the business info section for an ACN not an ABN so I can't put it there and all sales had stopped - what was the issue.... Technical problem - they will lodge another ticket with IT and get back to me in 48 hours. Today I get a cut and paste message saying that because we have not supplied the information they need ebay has decided they are not the right platform for us and we are to part ways? No reply at all to my follow up as yet but they have many 000's$ of our money and buyers orders are being cancelled automatically and refunded. The question is does anyone know  where we turn to get the several thousand dollars they are holding released - FOS can't help as they are not a regulated financial institution....OFT maybe if so anyone know which state - tried QLD where we are and they were not able to help because ebay is not an Australian Registered business   - anyone with any similar problems that can give a steer? Thanks all
