I don't have any experience with this film ... but I do wonder if it's a sign of what's to come with Kodak film since they sold the film business.

In any circumstance, it's bad business to send someone something other than what they ordered. I had this happen with a filter once at B&H. They didn't have the one I ordered in stock so they gave me a refund and told me to keep the wrong one, too.

Might be worth making a phone call.
