Algol,
Serious suggestion - when you go flying next run the software for a 33 departure and see what the EOSID text is. If that EOSID turns you left towards the terrain then there is an issue (or another issue depending on how you want to look at it!)
It may well be something as simple as someone, somewhere, has transposed the 15 and 33 text, which is why, when you tell the company about it they say and do nothing because they go and look at the raw data and say it is ok - thus ignoring your report/concerns.
It might not be that simple either, it could just be crappy procedure design, but it is another avenue of investigation to support your report
