As mentioned, I only received RM50 cash back despite spending nearly RM1,000 in November, but some other people did receive RM150 rebate. It is likely that the max RM4mil payout has been hit and higher-category products such as Amex Plat charge card and Amex Plat cc were given priority for cash back. Amex Gold cc ranks #7 in the product hierarchy indicated in the T&Cs.
