Several months ago I took a job where they required Google Voice to be used. All my voicemails would go to this voicemail. The company went belly up, I deleted the google voice account from my phone. When I tried to call my phone, it says that you can't leave a voicemail. I tried to power off and on the phone, and went to settings, reset and network settings, still can't leave a voicemail. Please help!
You might find help here, but as always, finding a Google phone number for support (other than Wallet) is difficult to find. But, you might find a link within your Google Account dashboard page.
