Where's the mobile phone forum?

[Digimont]

I'm trying to get help and have resorted to the TPG Community, but cannot find a category for posting questions about mobile phone issues.
- TPG Phone app, when I click on support takes me back to the login (when I'm already logged in).
- TPG "My account" does the same
- Online chat does not seem to be available
- I cannot make or receive calls (so I can't ring).
- SMS works fine, both send and receive.
- Mobile data works fine.
Network is set to auto-detection and showing as TPG (4G). I have 5 bars. Phone is a Redmi K20 Pro (doesn't support 5G)

Please help!

Additional: From reading of other people's issues...

My phone says VoLTE calls aren't supported by the CARRIER. I cannot access the setting to change it.

According to kimovil.com, Vodafone supports B1 (2100), B3 (1800), B5 (850) bands and my phone supports all 3.

I've solved the call problem myself (thanks internet). Meanwhile, the feedback about your app, website etc remains valid.
