Zero Help!

I understand your frustration. Dealing with unexpected changes to your account and receiving inconsistent information is incredibly stressful.

While I cannot directly connect you to a specific manager, I can provide you with some additional resources since you addressed you already contacted customer service. 

Here are some additional steps you can take to escalate your issue:

 * T-Mobile's Executive Customer Relations: Sometimes, searching online for "T-Mobile executive customer relations" can provide additional contact information or avenues for escalation.

 * T-Mobile's Social Media: Reaching out to T-Mobile through their official social media channels (like Twitter/X or Facebook) can sometimes be effective.

 * T-Mobile Support Website: T-Mobile's website has many support options. It may be helpful to look through their support pages.

 * T-Mobile's Webpage for contacting them: T-Mobile has a "contact us" portion of their website, that may provide further contact avenues.

When you call, be sure to:

 * Document every interaction: Keep detailed records of each call, including the date, time, representative's name, and what was discussed.

 * Clearly state your desire to speak with a manager.

 * Reference your previous interactions and the inconsistent information you've received.

 * Remain calm, but firm.

I hope this helps you get your situation covered!
