worst service. number stuck on private

Hi.<br> <br> So my number is stuck on private for quite a while. My number doesnt show when I call people. My phone settings are correct. Already tried this on few different phones. Even tried a sim swap. I've already called the call centre like five times. Either they say its sorted but its not or I give up for waiting over 20 min.<br> <br> Either sort this out or I start looking for another provider that can give cli. I.dont see why this would be so difficult to fix<br> <br>
