When I delete voicemails by any method (swiping, edit mode, trash can on individual VMs), they disappear from my VM list, but no Deleted Messages folder appears at the bottom so that I can go in and clear them. Consequently, my voice mailbox is full and no one can leave a message. If I reboot the phone, the deleted messages reappear and so I try to delete them again and the same thing happens. They go away but no Deleted Messages folder appears so that I can clear them! HELP! This is a business phone and customers cannot leave messages! HELP! HELP! HELP!
