Who I have the same questioned this topic

One day my voicemail indicators stopped working.  The next thing I know I keep getting prompted to upgrade to Visual Voicemail.  When I declined (I really do not want it)  All voicemail indicators disappeared.  I noticed a I missed a couple of calls and went in and manually *86 to get in and it says I have three voicemails I never was notified about.  Now, occasionally the "tape" indicator of a voicemail will show up in my indicator bar but when I click on the notification it asks if I want visual voicemail, if I say no, it just goes away and Does not take me to my voicemail!?

What the heck happened and how do I get it back to the way it has worked for the last seven years?  I just want my basic voicemail back!!!!

HELP!
