I have the same problem. Tried restarting, turning voicemail alert off and then on again, leaving another voicemail then deleting it but the voicemail icon is still there. Didn't have this problem until I received a new Virgin SIM card a couple of weeks ago.
I dont understand, why theres no any online chat or something to help people? Why it allways takes ages to solve the problem? I still got this icon on my screen. Its there for 6 weeks now. What I have to do? change the operator?
Is there a problem with Ghost Voicemail notifications now? I'm with Virgin and I can't get rid of the voicemail notification. Please see attached. Virgin suggest leaving myself a VM and deleting this new VM to clear it. Doesn't work. They also suggested deleting the phone icon' s data cache. Doesn't work.
I have started having the same problem for a few days. If a reset is required by a virgin tech can you please do that for me. I’ve tried all the obvious things (rebooting, sending another voice message and deleting) but no joy with that.
