I'd ask for the record of the refund from CX then wait another week and if it doesn't show up, file a dispute with AE forwarding the record to them.
IIRC AmEx will deduct the anticipated refund from the amount you owe and not charge interest and penalties, provided that the refund does eventually come through to your account. Doing this might involve filing a dispute/chargeback, so think carefully if it's worth it.
