Issues with service

I have been chatting with T-Mobile representatives since May 1st,2023 about connection issues that interfere with calls, texts, 911 band, clocks and pretty much every single thing you'd use a smart phone for. I have been told 2 separate things. One being that I'm at the very edge of service for 2 towers, both of which not being the one i can see from my upstairs windows, and that the devices are battling which one to connect to before just dropping out. The second one being that it's "upgrades to the towers." The first one took a little over a week and several tickets to get as an answer and the second was a very very angry phone call with a manager after a random and purposeful disconnect by a representative. I took a speed test and while having decent bars and on the 5G UC band getting 13.7Mbps download and 0.00Mbps upload. This is pretty consistent and if i go literally just 1 and a half city blocks, less than a single mile away from my home i get speeds over 300 down and at least 30 up. I have been told by SAMSUNG and APPLE support directly after they looked into devices that it is NOT the devices but is the cell towers themselves. I am unable to switch as I can not afford to pay the last bill and the start-up amounts for a new carrier. I can not afford to pay 700$ for an antenna when i can go about 100 feet outside my back door and get the same 300 down and 30 up. Is there anything anyone can think of? Especially as I have a device which someone had not with any protection on it made a literal 700$ paperweight due to a disconnect during a software update resulting in corruption of the OS that requires a full motherboard and antenna replacement on an iPhone 11. I know the solution is to just alter the tower antenna slightly because it's covering a lot of farm land or add another antenna onto the tower, which i can see from my upstairs window as stated before, but T-Mobile are not willing to do this from what they have told me. 

The device below is a Samsung Galaxy s22 Ultra. The other devices with the issue are an iPhone 13 pro, Samsung A71 and another iPhone 11 that luckily is not a paper weight. i did block out certain things for privacy purposes.
