Very poor 5G service

My partner and I are both on 5G EPP plans and are experiencing poor 5G data service. We have been on both Koodo and Public Mobile for years and it has never been this bad, which makes no sense since it's the same network. We are both using Samsung Galaxy S23FE devices with physical sim cards, on the newest version of Android. We have reset network settings on both devices and that has not helped. 5G preferred is selected. We are located in Kingston, Ontario. 

Hoping someone at Telus support knows what they're doing and can help us out here. I don't need entry level "have you tried rebooting the device?" type of help, I need proper support, because otherwise as soon as the Rogers RPP deal that I'm looking for is available, we will jump ship. Rogers service in the past has been exceptional in comparison.
