******* me, refuses to help and continues to pass the buck

Upgraded my contract for a galaxy note 8, when asking the lady what contracts there are she told me the ones most advantageous to mtn and not what I need. I feel ****** and hate the poor service. Subsequent to this I was told I have 7 days to change and must call ********** 667, I called numerous times and was either told they'll call me back or was sent to a different department who then sent me back to them. Mtn are slime ***** that have no concern for their customers. To date many people were supposed to call me back but I received no call, in addition the twitter account does not respond. I have deep regret in upgrading with this ******* company that has no concern for their clients
