Question Anyone experience this T Mobile error message that T Mobile can't solve?

[vigilant19]

Service Unavailable.
F451 : Uh-oh, it looks like we have our wires crossed. Please try again later.

I've lost PC account access to my T Mobile account for weeks. T Mobile 'engineers' have not provided any answer.

I tried accessing my account using a WIN 7 and WIN 8 desktop with Chrome, Firefox, Explorer, and Brave.

I've also lost ability to receive various text messages and voice mail messages with T Mobile who is telling me I live in a "dead zone" not serviced by local cell towers.

How competent is T Mobile given these problems?

T Mobile community said to login prepaid or post paid to login to avoid the error message I displayed above. Neither option works.

Well if it all worked before without you moving or some other physical change then "dead zone" is not the issue.

Contact T-Mobile and get some confirmation that your bills are all paid and that you are a customer in good standing.

When you say "Neither option works" more information is needed : what exactly did you do (or try to do) and what exactly were the results of that "try"?
