I'm using a Nexus 4 on Android 4.2.2 I asked Koodo to deactivate my (free) voicemail because I find voicemail aggravating at best and Koodo's service had been forgetting my password or missing keypresses (not sure which). I happened to have a notification pending when the service was cancelled. Now, I have a persistent voicemail notification which buzzes my phone every five or so minutes and won't go away. I can no longer try to check my voicemail to clear it, and clearing the app data only works for about five minutes. Can anyone help?
