does anyone have a listing of phone numbers to directly contact the delta sky clubs, specifically the boston location?

the reason is i have a sky club day pass that was stamped 15 feb even though i didn't want to use it. it's a confusing situation and the agent apologized and crossed out the date and wrote her name and said that i "should" be able to use it, despite it being stamped.

however, i don't like words like "should". i soon fly out of boston and want to call them and see if they'll accept it.

thanks!
