Galaxy s6 Voicemail notification will not go away

I am at my wits end with this glitch. I just got the Galaxy s6 last Friday and within a few days I got a voicemail notification that will not go away. I have tried many many things:

- clearing the cache under application manager (It will go away for a couple of hours or if I restart the phone)
- updating the PRL
- updating the profile
- calling my voicemail from another phone, leaving a message, deleting the message, and waiting for it to clear (it doesnt clear)
- Installing google voice, letting google voice take over my voicemail, and uninstalling it
- getting the entire phone replaced (yes, believe it or not, the issue still shows up on an entirely different phone)

So I am not sure what else to do if anyone has any ideas I am more than open. I have a Galaxy s6 on 5.1.1 with Sprint network.


Thank you in advance.
