I enquired using live chat. Put me on hold for 25 min then told me I am enrolled for Jan. I told her your system updated wrongly please check the date my SMS was received and request relevant team to correct it. Her reply "Based on the system there is no error on our end". Ask me to call hotline.
Hotline checked that SMS was received in Dec and none in Jan and confirmed I am enrolled in Dec cycle.
I guess I met a useless live agent. Next time will just call hotline.
Hokay.
Live chat agent, hotline CSO and their duty mgr, Service mgr, RM, plus the authoritative product team need to be on the same page.
And today is already Friday...
