Query: Bad DVD - defective and only partial refund!

I got this triple-movie collection, and Roman Holiday switched from English to Italian about 15 minutes into the movie! There weren't even subtitles! We could not watch it at all. I returned it as defective, and wanted a replacement DVD, but I was only given partial refund. Boo. What a rip.
