Well since DKF brought up work petpeeves. I am a voice mail administrator for a cellular company. I have worked on voicemail systems for 10 years and for 10 years I have heard the same complaint multiple times a week.
I got this email today from a salesperson.
Subject: Voice Mail Problem
Customer is complaining that when they recieve a call the phone never rings and goes straight to voice mail. The customer will not know they have missed a call until they get the notification of new voice mail on the phone. Please investigate why the voice mail system gets the call and not the customer.
THIS IS NOT A VOICE MAIL PROBLEM!!! ***pulls what hair he has left out***
If the call went to voice mail, and the caller was able to leave a voice mail, and the customer then was able to dial in to their voice mail and listen the the message left for them then guess what? FOCKING VOICE MAIL IS WORKING!!!!
