Just an update.

Following my post on the forun, Maxis called me on friday 6/11/2020 and told me that my number has been provisioned for volte on 2/11/2020

But i am very sure and confirmed that I have contacted maxis on 3/11/2020  and they told me that my number hasn't been activated for volte.

Then maxis staff asked me to swap my sim to sim2 (currently i am using dual sim, unifi prepaid with volte enabled in sim 2.)

But to no avail.

Then maxis asked me to swap to another phone. Same, to no avail.
Next, i followed maxis suggestion saying that there might be something wrong with my sim card, i went to maxis center for sim card replacement.

Same, to no avail.

The maxis staff then created a case for me.

Yesterday my phone received a monthly firmware upgrade. I was so happy. But still volte nowhere can be seen.

Today. I contacted maxis again. To make sure that whether my number is indeed volte enabled, the staff told me that NO.

You can see the way they reply to message. 4-5 Mins for 1 reply.
WOW. wasting my time.

Maxis should really look into this issue.  Their app live chat will be automatically ended when idle for 3 mins. But thier cs is taking a long time to reply. 5 mins. How may i help you. After 5 mins please wait... After 5 minutes i am sorry.

WhatsApp is even bad according to your experience.
