Dear Collette
Thank you for your offer of help, but help should not be necessary - it must be relatively easy to allow customers to switch voicemail off themselves. Then Virgin would never have to handle questions like this again, assuming the how-to information is made easily accessible (currently I couldn't find any documentation except through similar 'contact me offline' messages in the forum).
Just because something is free doesn't mean it is useful or desirable - in our case we have our own answering machine, and we had assumed that this was handling calls, so we never thought of looking for the voicemail. Consequently we missed several important messages that callers had assumed that we had received. Thus the 'free' addition was a major disadvantage for us.
Regards
Bob
