Demon`s limits. Dantalion?

Greetings you all. Id like to ask you, if anybody has ever evoked the goetic Dantalion? If so, would you mind sharing your experiences?? Also, his office is to "change peoples thoughts ", but, is there a limit in what he can do? I want to make amends with a certain person but that person is in a very negative set of mind, doesn`t want to talk with me let alone keeping seeing me…I was told there are limits in what Dantalion can do…

Did u used the search function?

Anyways I posted one of my experience with dantalion here : http://becomealivinggod.com/forum/general-discussion/hail-dantalion/msg69856/#msg69856

But the results were for short time and faded quickly
