IMO, from what you said, I can easily see why Berry's won't exchange it if it's a sealed package. (I have no idea how it's packaged) It definitely seems like Berry's should have reimbursed you for shipping both ways.
Screwups certainly happen.
Attention Brass rats and other reloaders: I really need .327 Federal Magnum brass, no lot size too small. Tell me what caliber you need and I'll see what I have to swap. PM me and we'll discuss.
