How do I delete a blocked voice mail?
I found a voicemail message that is blocked while checking a new message. It should never have been blocked in the first place. I have unblocked the caller and added the contact to my phone list. However, the voicemail message is still blocked. I have tried to delete multiple times. It appears to delete but when I go back to my voicemail screen, it is still there. How can I permanently delete this message? I have an IPhone 4s with IOS 7.1.2.
iPhone 4S, iOS 6
