No service in a full service map

We live in a neighborhood called Kemmer Ridge in Beaverton Oregon. It’s listed as having full coverage on all services. Yet, we have literally no service. Phones show 5g-1 bar and we cannot take phone calls at all. We just upgraded our phones before moving as well, so locked into 3 years without buying out the phones. Anything at all we can do to improve service. Or at least report? I’ve already been through all the eSIM resets and all that. 

Heard a rumor from a rep, they may swap to T-mobile towers since the business lines use deal? But is it possible to swap to business account? My wife’s extra line technically is for business phone. (T-mobile works perfect here according to my neighbors).

Any help or advice is welcome. But worried we just have to switch.
