Maybe going in person and arrange a meeting with both of them. Bring a copy of the e-mail you got from the person. E-mails and phone calls are OK but to me nothing beats seen the people's reaction in person. The director may not be aware of what the staffer is up to. You may be opening a can of worms, and I say go for it.
I wance donateda quilt to Stop Domestic Violence to be given to a victim, through my guild. Never though about it again. Months later I went there to deliver used phones collected at work and the quilt was hanging on the wall. My son recognized it. I asked about it and they told me they liked it too much to give it away. I didn't liked that because I knew that it was a matter of time before someone went home with it. I spoke to the director and a few weeks later got a message that hte quilt had been donated to a victim.
