Send an email to fleet admin or better still, next time you're in HQ call in and ask someone.
I've been into Flight Ops 3 times within the last few weeks and on every occasion, the lovely local ladies are normally either stood around chatting to each other, staring into their phones or just smiling nicely at you whilst drinking coffee at their paraphernalia filled desks. Not having enough time to help shouldn't be a factor!
Good luck!
