need help with contacting TMobile corporate office

Hi everyone, I took a chance and last night I posted my message on x.com(used to be twitter), and tagged the CEO and Tmobile official page. Tmobile responded and able to come to a resolution to resolve my billing issue. Just like you, I was guaranteed a set pricing of my newly upgraded plan with the free iPhone 15 after trade-in, and instead my bill for the past 3 months have been more than what amount should have been. I am looking forward to my next bill with the correct information now. They were also able to adjust my current bill to reflect the promised amount. So go to x.com, it worked for me, I'd like to think they will help others too. You can find me @krizzy_333, you can even reply to my posts they should see it there too. ¡Buena suerte!
