Vaya, no le he dado
Well, I haven't given you. I wonder what "no le he dado" really means here.

No le he dado importancia a la pregunta- I haven't paid attention to the question.
For sure, but what about Yo no le he tomado en serio. What is the le referring to do you think? Just leismo? I hope so. - jeezzle
"le", "me"; "te", "les", here is absolutely necessary to determine who is the subject receiving the action of the verb.
No le he tomado en serio: Subject? He-she
No me he tomado en serio: Subject? Myself
No te he tomado en serio: Subject? You
No les he tomado en serio: Subject? You - plural
Goes exactly the same way for "le he dado" (la importancia, un regalo, su almuerzo, whatever).
The Spanish indirect object pronouns are me, te, le, nos, os, les. The indirect object answers the question to whom? or for whom? The indirect object pronoun substitutes for the indirect object.
I guess I don't understand the reason for the "le" in there then. No le he dado importancia a la pregunta. No la he dado is what I would say. Of no me he dado even if I was using darse to realize...... No me he dado makes sense as an exclamation. No le he dado as an exclamation without any context (She sees someone and says it with exasperation) is wierd to me.
