How do I speak to a Supervisor regarding the poor customer service I have received. I have had nothing but issues since adding a line to my account. Activated the new line on Sunday 02/04 and it still does not work. Spoke to a rep this evening and apparently the line disconnected while on hold. Called in a second time using Tech Coach app and requested to speak to a supervisor when suddenly the line disconnected again. At this point I want to cancel my account. Been a loyal Verizon customer for many many years. Why pay an activation fee of $35.00 when my phone does not even work. This is completely unacceptable.
