Whilst it is widely known that Jeppesen can make the odd slip up and is not always on the cutting edge of technology they do usually respond pretty prompt to an appropriate moan (like yours obviously is)
Certainly in my experience they are usually pretty good and forthcoming to rectify errors on their part.
I would have said that your experience is pretty atypical and certainly does not compare to what mine has been, so ring them again and moan.
I usually ring the German office and deal with them direct.
I hated the paper updates so much that I got myself the JeppView thing. So much less hassle.
