Hi Rob. Welcome to justanswer.
There are some software available by which you can recover the voice mail messages. I am not sure if you will be able to recover but you can give it a try.
Reply so that I can guide you further.
First follow these procedures then I will try through the software.
Tap the Voicemail icon on your home screens
Have you tapped voicemail icon?
I am not sure about it. It depends if you still have that file in trash then it can be recovered. So first follow the steps that I am giving you. Recovering through software is the second option.
Do you have the voicemail icon on your phone?

Can you tell me Rob, were the messages voicemail messages or the audio recordings?
Which network provider are you using?
I am sorry Rob, Once the voice mail is expired (7 days) it’s permanently erased and can’t be recovered
All of them have disappeared?
Press 4 and check if you get any option to manage deleted messages
Access the advance settings and see if you get the option to recover or not as this is the only way. The messages are stored on the vodafone server and that is why we cannot recover once they are deleted.
Rob I would advise you to give a call to Vodafone and ask them if they can recover as they have the messages saved in their server.
I hope they will resolve this issue as they have them saved at their end.
