I am also unhappy that we have been updated on the status of the PCH, I also recently attempted to contact the company without any response. I would however attempt to give the CEO a little wiggle room as to whether or not he has missed his stated timescale for the submission to the FDA.
The term used in the AGM was "early 2016", if GK intended that to mean prior to the end of March he would most likely have used the term "First Quarter 2016", "early" most often is used with a view to the early, mid and late nomenclature and thus divides the subject in thirds. This would give Prana until the end of April before even the kindest of Prana supporters would have to admit that the target had been missed. The above having been said I do believe the companies owners (the share holders) are deserving of a better interface from the company management.
