Sometimes there is a ticket number on the booking which doesn't show up on the BA app (though this remains the best way to check). The thing you can try is the Finnair email receipt to see what it says:

I would probably leave it now to OLCI. I don't get the webchat response, it's not a financial transaction so they should be able to handle it. Try a Direct Message on Twitter, they can fast track ticket issue once the Social Media team understand your DM (and assuming they too aren't overloaded). Doing it at the airport isn't great but sometimes it's all you have left open to you. If you're OK to go back with JAL / get to LHR later than advertised then it may be the easiest option.
