Thats just how i was when i was in the job and its the only real way to do the job properly. Though there are always weak links in every chain. At t mobile i once called in to change the time settings on my voicemail, so the phone rang for longer before diverting, and the agent did not have a clue what i was even asking for, never mind how to do it. Imagine her surprise when i, anonymous as a customer, politely and patiently, told her, step by step, how to generate the code i needed on her system!
