Championing in Horde CIties, stucked at Thunderbluff(don't give quest)

Hi Everyone!!! I have been doing the championing in the horde side, and I made it up to the orgrimar, after that thunderbluff don't give me quest at all or either the sen'jin. I've checked my reputation for the horde cities i'm perfectly exalted to all. I thought that maybe by next day quest will spawn, but after months of waiting still nothing. So I decided to ask this and post this in the site. Hope you can help me. Thanks a lot and more power...Have a great day.
