So incredibly frustrated

Over the course of our time with TMobile, we've been continuously hamstrung with website issues when it comes to paying our bill. Today's commentary says they "got their wires crossed" and to just try again later. Nowhere else, anywhere, have I seen reports of services being down, maintenance being performed, nothing. I've tried guest mode, multiple browsers (and their private counterparts), and even an entirely different PC to make sure something wasn't wrong on our end. I can get to the homepage once, and the second I try to log in, it falls apart, and apparently hangs on to the attempt, because everything I try after that causes the same error to pop up. It's completely prohibitive, and prevents me from being able to access any necessary resources involving my account. We came to TMobile because it was cheaper than Verizon, and while I'd say "you get what you pay for" might otherwise apply here, $150 is not equivalent to the subpar level of performance we've gotten from our signal quality to the website. You tout yourselves as the "Leader in 5G" or however you phrase it; maybe shift some R&D resources into website service and stability!
