Anyway just sharing this in case anyone missed it:
Payments to the following merchants / merchant categories are not eligible for GrabRewards points, regardless if these payments are made using the
in-app GrabPay check-out option or using the GrabPay Card:
Money transfer or remittance service providers
Payments to banks or third-party mobile wallets

(including AXS)
The above list is non-exhaustive.
We are constantly reviewing these merchant categories and may add/remove categories in accordance with our risk and security protocols.
