T-Moble T Moble Refusing to give credit to returned phones, Theft, Calling place of business after being told not to call place of work, harrasing phone calls Fort Worth, Texas

T-moble sent me the wrong phone when I placed the order.  I told her I wanted an HTC and she sent me a nokia.  I returned the two phone at what she told me cost $200 a piece.  I certified mail reciept #70100290000061104683 in which Matt Barnet signed for it on Nov. 8 at 3:53 Pm.  T Moble still says they never recieved the phones in which I paid for the phones.  T Moble refuses to refund me the phones.  So ether Matt Barnet or some one at T Moble, as far as I'm concerned stole my two phones.  They and Amsher keep calling me at my place of work after I told them to stop calling me at work.  Amsher, after I told them to give me a detailed charge statement refuses to send me out a detailed statement.  I have no contract with T Moble and they have no signature from me.  Amsher refuses to send me a dispute form so that I can dispute the charges.  Amsher just wants to piss me off on the phone at work and not take any info or reason why I will not pay.  Both Form 173008624, and Form 173008640 was sent in one package certified mail ##70100290000061104683.  Sent by US Postal Service.
