T-Mobile Customer Service did a fantastic job!

I couldn't disagree more.  Followed your suggestion for the first dozen or so calls.  Now after spending 50+ hours on calls, store visits, chats, and social media, I can confidently state TMobile is unethical at best.  Customer support is anything but supportive.  I cannot even receive a mailing address or email to dispute fabricated 'late' billing on a cancelled account.  The account was closed May 3rd, yet TMobile claims it was closed Aug 9th.  However, they are charging me 2 months of past due payments.  Customer support has even put me on hold for 30+ minutes and hung up with no call back or explanation.  Worst company experience of my life, which is ironic because the actual service was a perfect fit.  I went from loving the company based on their products to hating the company due to their billing and support services.  What a joke.  I've requested investigations on the representatives that hung up on me or 100% lied to me stating all the billing issues were resolved only to later on self initiated follow up calls to find out a dispute was not even documented.
