Anyone else having untenable tower issues?

I've been having issues with my TMHI since the middle of November, roughly. They've done tower maintenance twice since then and I honestly feel like that's done more harm than good. I routinely get extremely low speeds and even worse, 400-500ms latency. The jitter is also really bad. I've tried moving my tower around my apartment and that didn't help. Its near a window on my desk currently. There's a tower just over a quarter of a mile from my location. I understand that certain types of traffic are prioritized during peak and high load, but this happens all the time to me, I've had it happen in the morning, in the midday, the evening and night, and even at 3 in the morning. I've swapped out my box (FAST 5688W) for an identical unit from the T Mobile store, and that has not helped. Hell, I'd love to argue for some credits back to my account for how often I find myself on my Verizon phone hotspot or the Cox hotspot.

Can any support agent help me get one of the G4AR/G4SE units? I'd like to see if an external antenna would help. If not, then I'll probably be cancelling my service and going to Cox. What's the point of paying for a service if you can't use it ¾ of the time? 🤷🏽

EDIT: I forgot to mention that right now the download speed is really good for some reason. Also, the packet loss test didn't even run which is new. Send that to your tower engineers, maybe..
