Why doesn't that surprise me?!
I know from experience that TVOC only communicate with people when they want to, and as soon as they can't be bothered or when they think someone might be inclined to ask some difficult questions, the lines of communications go dead. It's a sorry business.
I'm glad that you've said what you think and I hope others do the same too. I don't know why everyone seems to be so reluctant to point the proverbial finger at TVOC's management - maybe it's some sort of fear that if too many questions are asked then the whole project might come tumbling down? But let's face it, I think we've reached a stage where it's starting to topple in any case so if there's anything we can do to prevent things becoming even more dire then let's do it, don't you think?
Surely, we have the opportunity here on Pprune to gather the "serious" people together and combine our talents in order that we can demand some sensible dialogue with TVOC and/or HLF? If we don't then who the hell will?
