Lately, I have not been getting voicemail notifications or getting notifications when I have no voicemails pending. Yesterday, I received a call and when I checked my voicemail, I had 11 (ELEVEN) voicemails waiting. They were from up to 5 days back! Many of these were very urgent messages that I missed and have lost income and possibly future income because I wasn't able to check the message. Even when I check my voicemeail after a missed call it will say I do not have any voicemails. Eventually, up to several days later, the notification will come in. Is there a resolution to this problem?
