Let me know how this going on...
Just to update you, I successfully paid my Maxis Bill today.
So how does it works?On the Friday, you might need to call CS billing department (call 123 > press 2 > press 1 > wait them to connect you to their customer service) to let them know you want to pay your bill on Saturday using AMEX card to enjoy 5% cash back (to avoid them to ask you why not on that day itself

) and ask them to arrange call back from AMEX team on Saturday.
Two possibilities might occur:
1. If you are lucky enough to get experienced staff, they will arrange for you immediately.
2. Else, they will tell you AMEX team is not working during weekend. In fact, AMEX team works half day on Saturday.
So if they insist, you might need to call second time like I did
So today I received call from Maxis AMEX team and successfully paid my bill and enjoy 5% cashback from maybank amex
