is it only me who cannot pay online celcom bill through celcom ocs website using amex?

or is there any way to use amex pay celcom bill?

btw, can use visa.

just got RM50 for i love m2c cashback for both card.

thinking of terminate other cards HLB & AEON.

and just sharing, Bank see credit card owner as not good and critical if they use 75% and above their credit cards limit combine. if not pay even minimum payment OR late payment, of course also not good.
