I have been having a billing problem since I first subscribed to FIOS 13 months ago. For the first 9 months it was dealt with by having a credit issued. Since Verizon converted to a new billing system last fall, I no longer recieve the credit. Four months of calling 1 (800) 837-4966 has not resolved the issue, despite promises to do so. During the last call I was told the issue would be escalated and I would be contacted. It has been 45 days and no one has reached out to me. Further, my bill is still incorrect. I have an email from when I first subscribed that states the facts regarding my plan and billing details. The first line customer service reps can see the case notes, but apparently cannot fix the problem. Further, they refuse to connect me to a supervisor. Please help. By far this has been one of the worst customer service experiences ever!
