bad service

To whom it my concern<br> My phone recently got ******. I called customer care they asked me a few questions. I managed to answer 3 questions correct out of the five. The agent rep**** by say say they can not help me. All the information is on the phone that is related to there questions which I do clearly remember. I called in about three times still no help by a network provider that we as customers so trust to help in case's like this. All my personal information is on the device including my mobile banking which is critical. Can some one please help.
