Hi

I am trying to find a way to reset my O2 voicemail greeting to the
default. I have tried 1760/1750 switching off and on but it comes
back with my personalised greeting.

O2 have said there is no way to do this. Surely they could delete my
mailbox and reinstate it somehow?

I am expecting a call from someone I do not want to know it is my
number is the only way to for me to get someone to record a greeting
for me or buy one of those fake messages?
