I will not pay my contact until I get a new device

I had problems with this device ever sense I got it, 10 Days old and it needed a software update and they gave me back the device and it was still getting hot and doing ****! the took it back and come back to me with the same device and tell me I cracked the screen. when techs at the Samsung said to me its a hardware fault and they need to replace you device. Khaleel Takay been the Regional Manager never contacted me until today, he has the dam cheek to send the device with the branch manager in august 2014 to my work place with the box opened and apps on the device as if its a new phone but instead its second hand, I said I will not pay my contract until I get a brand new device !! I have the screen shots of the apps on the device as proof.<br> Its going to be a year soon and I'm still stuck with the same ****ed up device , the branch at Clearwater wont take the phone because they know what khaleel did by giving me the second hand device, they said I must wait and speak to me he will be coming soon, he know got a new thing now by not taking my calls. If you guys can't help a client and its been almost a year now, cancel the contact, collect the device and pay the bill outstanding!!!
