2 weeks ago I spoke to a customer service person who was going to help me upgrade my phone a few weeks early. She told me to contact her and sent me a message with her email. When the time came I emailed her and have since emailed her 3 times in the last 2 weeks and have not heard from her. I don't understand if there is a barrier preventing her from contacting me or if she is unable to help me. Either way I would really like to know what to do next...do i need to call and speak to a supervisor?
