Audio Language of a Film

I purchased a film (Incredibles 2) on iTunes in 2019. We are from the US but live in Germany. I'm the only one in my family who knows German well. PLUS, the original audio of a film is much better than the dubbed version anyway. Films are meant to entertain. I watched the film ONCE with my family. I'd assumed we'd be able to watch it again. Not so! The audio track of the film is NOW only available in German. It is now unenjoyable. Silly me, I thought that once a film appears on iTunes AND I purchased it that I would have access to it, so I didn't download it. The answer seems to be a resounding "No!" to both counts because I get the runaround every time I attempt to resolve the issue either with a refund or with the film in the original language (which was present when I purchased it). I explained it to the people at Apple. They seem to think that English subtitles are adequate replacement for an English audio track. Apparently, they've never watched a film with subtitles before, especially, a family movie. Kids don't read subtitles! If it were a bad movie, it wouldn't bother me as much, but this is one we'd assumed we'd be able to enjoy again and again. Unfortunately, this isn't the case. How do I resolve this issue?!
