This has not been the case for me and I subscribe to "Premier Service".
I must always ask (usually more than
once) for updates to the "Mechanical Systems" and "Time Series"
packages. I have tried to get some help with
what I believe to be "bugs" in the "Time Series" package and have
received NO HELP from the developers of
the package (My first request for help was well over a year ago).

Not the case for me --- for several of the packages that I have purchased!
The best source of help for me is this very active MathGroup which has
so many Mathematica experts (e.g. Andrzej Kozlowski) that donate their
time to help the non-experts like myself.
