Yeah you're right about not being able to do anything. And believe me I have posted numerous times. As so much as to be accused of being a troll. Understandably those people were trying to help, but slinging mud doesn't help a frustrated customer.
In my situation TMO admitted to fault of error on their end, yet avoid rectifying it. Any way you look at it shows poor appreciation towards longtime customers.
If they refer to an email address(CRResponse@t-mobile.com) to submit a complaint, save yourself the hassle. Basically gives same response as regular CSR. Still I stay persistent to fight for what's RIGHT! And will continue until mutual ground has been met, satisfying both parties.
