I am extremely frustrated with Verizon. It is nearly impossible to speak to an actual person. I came home today and my phone was blinking and showing that I had a new VM message. When I pressed the VM button on my Panasonic phone, instead of entering my four diget pin, I was asked to enter my mailbox number. That has never happened before. I never had to enter my phone number unless I was calling in from another phone. I listened to my messages then I erased them. The light kept blinking showing that I had a new voicemail, but I did not. I tried several things but nothing worked. The phone keeps blinking showing I have a new voicemail. Any help will be most appreciated.
Sounds like a problem with your phone, not Verizon voice mail.
You should make sure the "voice mail" button is programmed with the correct numbers to access voice mail (usually *86)
As to the message waiting indicator, sometimes phones miss the signal to turn of the light. Most phones have a menu entry that will let you manually turn of the light. Check the manual for your phone if you don't know how to do this. Google may help as well.
