I turned my phone on this morning and I saw that I had two missed calls and two voicemails on my phone, but when I go to the voicemail section on my iPhone6 the messages are not there. I checked in missed calls and the calls where not there either. I go to call my voicemail manually and the voicemails are also not there. I didn't think anything of this, but other people have told me they left me voicemails or called me and nothing about those calls are showing up on my phone.
