Samsung executive customer relations department has the worst customer relations employees. The are unable to answer questions about broken products and revert back to a scripted answer that does not apply to the questions. When the employee named Evens employee number 50213 or so he told me, could not answer my question and assured me that there was no one above him to answer my question after asking to be transferred to his supervisor, he hung up. I was shocked as I was very polite and remained calm, did not raise my voice or use any profanities. I phoned back to get an email or contact information as to where I can submit a review of the recording and file a formal complaint and it took three more calls to get access to an email. I emailed on January 5th and followed up on January 14th with no response, not even an automatic reply. I do not recommend the Z4 flip phone as they have multiple problems and Samsung will not fix the overheating battery, or bleeding screen even under warranty. the worst customer care I have expereinced
