Tower upgrades, but let’s make it take 2 years???

I have been with T-Mobile since 2021. First year I had no issues at all where I had lived until the last 5 months I lived there. I moved 2 hours .140 miles. away from that town back home. For the last two years I have received the absolute worst, most unreliable service while using data when i travel .300 miles way MAX. I can't make phone calls, texts can take hours to go through, I can't get directions, use google or safari or literally any app that needs wifi or data connection. I have called several times about this issue and now it's also happening in my homebase. Every time I call I get told this is tower upgrades…these take 2 years!? But the rest of my family is in the same town I am and travels to the same places I do and they don't lose service and are able to use their data sufficiently and reliably. Why is this only an issue I'm having? I've visited countless stores as well and they don't know why this is happening, as a last resort I upgraded from my iPhone 13 Pro Max from 2021 to a 15 pro max this year 2024 and the issue has gotten severely worse. How can I be the only one in my household of 6 having this issue in several towns and at home? How can the towers be the issue for two years? T-Mobile can provide mediocre "excuses" provided unstable, unreliable, insufficient services but dang if we don't give them their money each month.
