TLife app doesn't allow me to download documents

Okay, TMobile is a large tech company specializing in wireless coms, right?  Yes, this is true. So how is it that this TLife app that the company is jamming in my face unable to allow for the download of documents? If I click the download link, it changes color like it will do something and yet does nothing, nothing at all. So when I, a customer, am faced with a situation where I need the f#%king documents to show that TMobile is not living up to an agreement they made with me, I'm out of luck. Yet, without fail, your f#%king payment portal always works. The sales apparatus, always works. But when it's a thing that benefits customers TMobile could not care less. Can't you fix the app so that it does what you claim it will do? Or is it merely the claiming of a function good enough, no need to provide one. Is that enough to keep the government out of your hair, TMobile? Can someone provide a working app, please?
