A Sprint store had to do on a reset on my LG G Flex and all my voicemails got deleted and I did not know this was going to happen, I thought that If i just call my phone number it went to my voicemail and they would still be there but nope they were gone!!! Is there any way at all possible to retrieve my old voicemails there were some very important ones that I needed?? Please help me get them back??
