First I'm been with T mobile for almost 11 years. I get a upgrade foe one of my lines,and trade in my old phone. 14 months later I realized I have a extra line on my account, so I question it,and the TEAM MEMBER told me of said line. And informed me I would not be reimbursed for the overcharge! That's really unfair t charge someone for something they don't have or know about. What do you do?
