After talking to several people and hearing them tell me that they called and left me a voicemail, I decided to call 1 on my phone and lo and behold, I had more than 40 missed voice messages. NONE of which I was notified or had in my visual voicemail. When all is said and done, I haven't received a visual voicemail or a notification of a voicemail since June 30! What is wrong with my phone and how can I fix it? HELP!!!
