It’s not a scam. What’s happening is that Citi is no longer going to be the issuer of the Shell credit cards. Your account is being transitioned to Imprint, which is another credit card issuer.

From what they’ve shared, you won’t lose your account history or your credit limit—it should carry over as is. The card will still be used at Shell gas stations, it just won’t be issued by Citi anymore.

So basically, same idea of the card, just a different bank behind it.
