My phone not ringing only with o2 network

[HAOS]

hello!

i want to use my samsung 7 with my account.

The phone is working correctly on other networks, except o2.

I can make calls and text, receive txt as well, using data but not receiving phone calls

I want to have this sorted at the earliest convenience

Please explain
