Zero outdoor service on Military Rd S, WA

Since JBLM closed off their tower a year ago to non-military cell users, T Mobile has made no attempt to build a new tower. That means that Spanaway Park and Sprinker Center, local parks, have no 911 service despite encampments with fentanyl and meth users inhabiting the neighborhood.  I spend most of my day outdoors, and disabled and am a fall risk. The lack of cell service here is dangerous.  Besides complaining to the FCC, what else can I do? Tech support said to buy a new phone.  I have a brand new  Apple 15, and am very angry about my needless purchase. No modernization is planned in this area despite several T Mobile employees telling me there are two towers planned.
