Hi Guys,

I'm in a conflict with OZ, I had a USDM ticket (trip already completed) , and they claimed the reason for them (OZ) not alerting me about changes leading to downgrading was that I had "no phone number listed" with US, which I know the Agent asked me about when making the booking but now I'm at a loss on how I can prove that was the case, I'm no longer able to pull up the details online since the trip is completed.

1) Does anyone have a clue on how I can prove that there was contact details on my booking?

2) Does anyone have any insights on how USDM pass on this relevant data on to the *A airlines during the ticketing process?

My thought is that OZ should be able to see that this was a US stock ticket on the ticket number and reach out to USDM to get the phone number or in case that was truly missing get an e-mail address since that I'm sure US Airways had since they sent out e-mails first when the ticket was issued and secondly when Luggage information was changed.
So no phone number for me is a lame excuse even if true.

My problem is that OZ uses this as an excuse to wriggle out of their obligations according to EU regulations.

So any tips on how I can prove them wrong is much appreciated!
