Without our permission, following a fraudulent charge on our account, American Express changed our "Blue Cash" credit card to an unadvertised "Blue Cash Instore" card with much lower rewards. Be very careful, as the new "Blue Cash Instore" card is identical to Blue Cash. Over several agonizing hours on the phone over many days, representative after representative acknowledged that the new card is not as beneficial as my previous card as well as admitted this was an error made on their part. Two representatives had no idea what "Blue Cash Instore" was and after checking with someone else, told me it must be the same card. I was told that I would have to apply for a new card. We thought for sure they could resolve this error, but would only do so at the customer's expense. Does anyone else have this unadvertised card? It's nowhere to be found on their website or anywhere on the internet.
