everything was working fine as far as i can remember with plusnet mobile and my sony xz then a few days ago my dad rang me and I couldn't get to the phone in time so he left a message on my answerphone.
after this point I'm contently getting answerphone alerts on my handset that is really annoying
so far i have tried
clearing all my answerphone messages including saved ones
dialling **004*+447870020555*11*30# OR **004*07870020555*11*30#
contacting plusnet (always a mistake!) who stated its a issue with my handset go away and bother sony
contacting sony went through a whole load of stuff including rebuilding my phones software.
back to plusnet again who advised i disable any alerts but i noticed that then i would never know if i had a message so the adviser said she would reset my voicemail but low and behold she just turned it off but i still get the alerts!
as soon as my phone reconnects to the plusnet phone network i get an alert and i now don't have a working voicemail service! what is going on?
