It is not only SW who behaves like that. I had some questions for the medical card people. No answer either. The usual " Send us in your application and we make a decision". Those agencies treat grown ups like kids.The attitude is ridiculous given how imprecise the guidelines are often written.
I had a technical query regarding PRSI rules years ago that DSP would not answer.
The only way to get an answer was to get a TD to ask a parliamentary question.
