Mytm and newer
https://unifi.com.my/ are different systems, you can't use mytm login & password on unifi.com.my. Mytm is still accessible for some reason even though TM CS told me that TM is no longer updated Mytm anymore.
I don't understand why paying TM bill at different checkout systems will have different results for CB entitlement, I suppose TM bill is not categorized under utility, so it should be safe no matter where you pay it. Is it because the different systems will give different merchant ID and description?

i know it's a 2 separate system. interestingly you can login to mytm, whereas i always get redirection back to unifi.com.my
anyhow, the cashback mechanic for cc usually dependent on 3 things:
1) MCC
2) Description
3) Channels
all these were setup when you create new merchant ID with the payment processor.
since TM launched new portal, unifi.com.my, either they created new merchant ID or maintain previous. based on the description
TMONLINE(EC) KUALA LUMPUR MY with MCC 4814 (fax/telco services), they maintained it.
remember that merchant (e.g. TM) may create new merchant ID, especially when they are doing rebranding exercise now. who knows they itchy wanna display different name, like UNIFI ONLINE(EC) for example, or somehow think TM services are utilities in nature, then assign to MCC 4900.
also the MCC associated to it. if somehow wrong MCC was assigned, e.g. MCC 9399 (Govt Services

) or MCC 4900 (utilities), it could be excluded by PBB due to this reason as well.
this is why we always call CS to find out the MCC for any new merchant, location, etc etc
