Thanks for taking the time to post to our community! Let me see what I can do here to answer all your questions.
1- To me, this sounds like an issue on our side where your phone number and online account have not been fully linked. For this issue, we will need to speak with you over the phone so that we can get a help desk ticket opened up with our web support team.
2- Do you by chance have a prepaid account? If so, the T-Mobile app is not available for prepaid accounts at this time but we will make it available as soon as we have fine tuned the experience.
3- This sounds more like a browser cache issue where the links you are clicking may have gotten mixed up. My suggestion would be to either try clearing your browser cache and cookies or trying a different browser.
1. I'll call when I have some free time
2. Yes, I do have a prepaid account.
3. I have tried multiple browsers on multiple devices, nothing is working.
I am having two of these problems as well.
I cannot connect to chat as an existing customer. I keep being redirected to my homepage as well.
Customer service told me that I should be able to use the T-Mobile app with my prepaid account, but it is not working, and I read here that it is not possible. This is confusing.
Same problems - no matter what button I click on the prepaid.t-mobile.com website, I always get re-directed back to the homepage. Since the app doesn't work either, I am unable to view my account or useage data.
