Some genius at Rome's first Rent-A-Chariot noticed that most customer problems were caused by the customer and/or could be resolved by a low-skilled customer service employee. Thus was born the modern multi-tier approach to customer service. The people at the first tier go through usual-suspect stuff and FAQs, solving many problems. Problems not resolved then get passed on to the next tier or two where more skilled (and higher paid) people help with the problem. This is frustrating for people who know their problem is real, and not FAQ-grade, but, properly organized, the multi-tier approach solves a lot of problems quickly, and the higher skilled and paid people aren't wasting their time with FAQ-grade and user-stupidity-grade problems.
This DU-member's case being with a government department (or regulated monopoly) and probably speaking with union clock-punchers ...
