silent voicemail
my voicemails used to work fine yk "welcome to ur voicemail u have one new message from 07...." then then message plays and now when i try to use it I ring it and it's just complete utter silence. nothing. idk if the voicemails I'm recieving are silent either but it's literally nothing and it's very frustrating because I'm trying to go to uni and what if they are calling about something important?? how the hell do I fix this please 🙏
