It's odd that they gave you a hard time for the French packaging. I bought the French version on Black Friday and traded it in at my local EB Games and they didn't even bat an eye, just scanned it and continued on.
Yea I wasn't expecting that either. The rep was training a new employee on how to deal with trade-ins however, so maybe he was being extra careful or something.
So I received my copy of Overwatch in from Amazon.ca today. Turns out they sent me the bi-lingual cover. Could have picked the game up at walmart last Friday afterall. Missed opportunity.
The copy I picked from Best Buy in store has a bilingual cover too.. strange.
