How do I contact someone in upper management that has authority to correct issues on my account? I have spent 3 hours on the phone today with various agents, had my calls disconnected, been told they cannot transfer me back to the person I was speaking with, been told they cannot transfer me to a supervisor, among other things. I have been given misinformation from at least 4 agents and can't seem to get anyone to fix the issue. I have been a loyal customer to Verizon for many years and the customer service in return is astonishing. My calls get disconnected and noone calls me back, why do they ask for a callback number then?
