No 5G network coverage

So before joining iD mobile, I read their website which says they cover 5G network. So I went on the Coverage checker as-well as the status checker which stated “Yes-5G is available, you can use our 5G network for mobile internet, calls and texts”. So I bought the sim and I was on 4G not 5G. My phone is 5G compatible as it’s the iPhone 13 Pro. I contacted support chats several times and had done all the troubleshooting which was required of me such as, going out of my area 1 metre away, resetting my network settings, turning on airplane mode off and on, updating my phone to the latest updates, switching phone off and on, setting my network settings on 5G auto or 5G on. As well as, picking iD instead of automatic in my settings. After doing all that I’m still stuck on 4G. The support chats had said that yes there is 5G available in my area but apparently there was an outage. So I would need to wait for that by checking the status checker. So now that I’m up to date with the status checker and there’s no outage message it now states, “Our system has not reported any system issues” and still no 5G. The WiFi in my area for wifi networks are 5G. Previously I was on 3 mobile and my area was 5G but soon as I move to id mobile there’s no 5G. So I spoke to support chats and complaints recently and they are saying I do not have 5G coverage. When the website states otherwise. I feel like iD mobile shouldn’t say on their website that I have 5G coverage when I apparently do not as they are not providing the service that they  are advertising.
