I was using Google Voice for my VMs and missed a call. I got a notification through GV that I had a voicemail and then one from my carrier (which I don't use) saying I had one as well. When I went into my carrier's VM and tried to delete it, it said I had no messages. From there I changed my voicemail service from GV to my carrier in hopes I could get an actual message on there, delete it, and all notifications would go away. Unfortunately, I kept getting voicemails to GV, despite telling my phone to use my carrier. It's been about two weeks now and really starting to get annoyed at that notification on my screen. Any ideas how to erase it?
