AMEX CS rep gave incorrect info
I called in to cancel my Platinum card and the CS rep asked why I am cancelling. I said I recently got the Morgan Stanley version. She asked why I prefer the MS version, I said a free authorized user card. She told me that the MS version does not have this free option, only the companion card. At this point, I said I am happy with the MS version, please just cancel this card.
I am surprised that the CS rep would make such a mistake.
