Important problem about Succubus

Hello guys, i am level 70 warlock that dont have Succubus quest. No trainer directs me to this quest. What is the problem ? How can I solve this ?

Edit: I am on horde side

Bump guys.... This is so important to me. Anyone know solution for this?

Tried main cities/barrens?

Done, the problem is solved. Problem was, when i was leveling and training my skills from Orgrimmar Class trainer, I took Succubus quest from him, and he gives me Completed quest near him and when I complete that, he sends me to a guy from Orgrimmar also and I did this part while leveling. Then I just abandoned the quest. So I was searching quest in wrong places. The quest was in Orgrimmar but on the guy who I abondoned his quest.
