Mofoho,
I can fully understand your frustration but in future probably best to just kick the sofa or something - probably less painful in the long run!!
Most people on this forum are wonderfully helpful and even the ones who have crticised you have MOSTLY given some reasoning and insight into how things work. Don't underestimate how small the world is - in 2005 a certain poster from here (now working on foreign shores) arranged me a visit to LATCC (which I found impossible to do alone) and last year the HR lady at the interview asked me if my screen name was smellysnelly2004 and another perennial poster on here was one of the interviewers!!
You may have got some harsh responses but ask the right questions and people will help you. I'm no ATCO (yet) but am starting at the college in March and if you have any questions about interview etc, PM me and I'll try to help.
