Stand in line.  Expected wait time is 22 years and counting. 

I've been asking for some Maryland changes since 2005 and still no luck. These changes were "required by law" and still ProSeries did nothing.  My two clients would go down to the Governor's office once a year and hand them the tax returns in person even though they were required "by law" to e-file.  Finally, the Comptroller's office created a waiver form we can use because they realized tax software companies (not just ProSeries) weren't being compliant.

You will find more than one (maybe ten million) complaints about ProSeries customer service on this board.
