I have been in contact with Verizon regarding my last bill over 5 times in the past few weeks. I was overcharged on my last bill and was issued a credit which is "pending approval". In the meantime, they have sent my account to a collections agency. I am unable to get through to speak with anyone who can move this credit from pending to paid. How do I file a complaint or get through to a supervisor who is able to actually rectify and correct the situation?? TERRIBLE CUSTOMER SERVICE !!!
