Good afternoon @elbow99
A very warm welcome to the forums and thank you for taking the time to post.
I am sorry to hear that you mum has had some issue with the automatic voicemail, I really do hope that she is alright after her fall.
I will be able to help with getting this sorted out, I will need to pass DPA with you, In order to do so I am going to drop you a PM so that I can get some account information.
Kind regards,
Zak_M
