I have a Samsung note 3. I've had premium visual voicemail for years now. For the past year or so I haven't been able to access it. This happened once before and after about 2 hours on the phone with tech support it was fixed. A little while later, it stopped working again and so I've been without (but still paying for) premium vm. If I try to fix it through my phone it wants me to sign up for basic visual vm and delete most of my vm messages. Getting hold of the right customer support is always a pain. Anyone know how to fix this or have any idea what the issue could be?
