I had two text messages disappear from a Galaxy S4 that had important contact information (which of course I didn't have backed up). I can estimate the date and time that the messages were sent fairly accurately. They were sent from my phone to my phone as I didn't have pen/paper at the time. Is there any way to recover them? I have no idea how they were deleted, but they're definitely gone. I have tried repeatedly to find an e-mail address for Verizon customer service without success.
