I called Amex to cancel my SPG card which I opened a year ago and just got hit with the AF. The rep enticed me to stay by offering me 10k points, with no commitments needed, just that I don't cancel the card with her right then on the phone. I immediately accepted the same offer, and had her grant it for my wife's card as well. The points have since hit my account, and I want to go ahead and cancel my card. Can they be pulled back now that they hit SPG? Should I transfer to Marriott just to be certain?
