Maybe they could put you in touch with the KLM "Ground Services" you seek? I am unsure what you mean by "Ground Services", as I have never heard of such a thing.
Also, you could try KLM CityHopper BV (in the logistics and storage directory for Schiphol airport).

Maybe they too could put you in touch with the people at KLM you want to speak to?
