T-Mobile customer support and the tech cleared cache from the phone. This did not work and the technician reset the phone to its original state. The smart phone is still not operational. The technician then proceeded on offering to send a used “replacement” phone to me. I have asked for a new phone, since my phone was only 2 months old. I was told that that was not possibleT-Mobile, they even suggested we must have sent back an empty box and still have the phone. Finally we got an email address to forward the email we got from their warehouse that the phone was received.
