It's not HDFC. It's Amazon. Amazon pay has been removed from every redemption portal. Even SBI Bank Rewards Portal.
@aashuuuu yeah you are right. Uber pay with amazon wallet had some cb as agv, now they too are rewarding as Uber cash instead of agv idfc rewards too removed it credence and other portals where we buy agv too stopped them. Seems amazon might want to make it exclusive for themselves.
It is still an ecosystem where both AGV and CCs need each other. Without CC based rewards, people will stop buying AGVs itself and shift to cashback cards on other platforms.
