None of the options suited me so I ended up cancelling the ticket thinking that I could book it either by calling Austrian/United/TAs/OTAs but the fare bucket I was booked was not available for sale by Austrian!! The available fare buckets were pricing at a much higher price so I am looking into alternative options.
So now trying to find alternative routes.
Currency is always based on the departure point of first flight. Since you flew out of LHR, the fare is priced in GBP. If you flew out of CDG, it would have been EUR, etc. It doesn't matter which website you use, airfare gets priced in currency based on the departure point of the first flight.
It sounds like there was stale fare class availability. It's the reason when an airline tickets flights on a non-partner they have to wait for confirmation before ticketing.
