For whatever reason my iphone has decided to update itself without my permission. In doing so I've lost several very important voicemails that I have saved in there. I've called *86 and it numbered off all the voicemails that I had in there but for whatever reason wouldn't go through them all. When I called back there were only 17 that it had went through the previous call though I did not delete the any of the others that it wouldn't go through. These voicemails are very important to me! Any help would be appreciated
