Unhappy customer Brenden phillips

<p>Good day After many years of having a contract with mtn I am very unhappy with the service. I upgraded my contract to the Samsung s7 after using it there was a thin crack on the camera but I was still able to use it.after a couple of months the battery overheated and exploded. So I sent the phone to Samsung to repair and they now tell me they unable to repair due to negligence. How is this my fault.my fone is practically new i don't think it's fair that I have to pay for this as it is still under warranty.</p>
