T-Mobile T-Mobile hidden charges, I do not own phone! Nationwide

About a year ago my wife got a new LG Tone phone. It did not work sowe took it back within 48 hours. She exchanged it for a Galaxy S5. I happened to check my bill today and find that I am paying, and have been paying $2.91 per month for this phone. I called the idiots at T-Mobile and of course got someone in India. I told her of the problem and she just started talking about other matters that I had not called about. I was put on ignore several times and after telling the idiot several times what I was calling about she tells me they will have to investigate and make sure they have the phone in their warehouse. I went off of course and told her what I thought of her and T-Mobile. Stay away from these losers. All of the mobile companies are bad but T-Mobile is among the worst. There is no support! I was threatened by a manager of a local store. I will take care of him at a later date. My fight with T-Mobile is far from over. Be careful of what they do. I have filed complaints with the FTC and FCC but they are as useless as T-Mobile.
