My friend had a similar experience when her OH died and she was attempting to put the service accounts into her name. The young man kept insisting he had to speak to her OH! Eventually she asked to speak to a supervisor who immediately told her the young man was right!
I have found myself in some extremely frustrating situations trying to deal with service providers, but not as bad as that. While it is crazy enough to be funny, I can only too well imagine myself in that situation and just the thought makes my stress levels rise.
