Just a suggestion from personal experience, but take time to consider the comments you make to, and questions you ask of JPAC. I naively told them with my first fault that I thought there was a problem. They confirmed the problem and so closed the call, having "solved" my report.
So the next time I distinctly phrased the questions in terms of how and when they were going to solve the problem, and specifically told them that confirming to me that a problem existed would be insufficient as a reply to close the call. I was overwhelmed by the number of call backs I received to resolve the issue.
I guess I was lucky with only having had 2 problems so far, compared to some of you. But if you act as an intelligent customer with challenges to them that cannot accept a yes or no answer, they can't wriggle out of it so easily.
