I don't recall hearing it was any kind of "preview" when it kicked off in June, I was just amused that every year it begins earlier and earlier, with the same name attached..
I suppose too it's possible that they have a lot of new employees since June, since they want everyone to use automated returns and ordering....so maybe the person you spoke with doesn't know of the policy.
Anyway, when Christmas in July starts on Easter this year, I'll be sure to listen extra close!
Hope you can get it resolved......have you looked on You Tube for videos of the particular shows you bought from? Just put in QVCTV and you item name and see what comes up that was broadcast in June of 2022.
You may be able to hear their CIJ return policy in the broadcast.
