Have noticed some issues with voicemail and not sure if this is an issue with my phone or a system issue. When I receive a new voicemail, I get a notification called "16 Voicemails" with "New Voicemail" underneath that. When I click the notification, after it checks for voicemails, it pulls up only one voicemail which I listen to and delete. The next time I get a voicemail the notification says "17 Voicemails" and so on, 18..19. But always only new voicemail. Also, I also have had multiple occurrences where I have listened to and deleted a voicemail and the next time I come back to voicemail, messages that I deleted are back again.
