Legion Captive Wyrmtongue Not Selling

Ok, I know the prelaunch is WAAAy over, np, it’s just I had some fel infused stuff to increase the weapon levels, and well the seller has absolutely nothing to offer anymore, which I think is kind of STUPID ! The thing is the household decided to QUIT wow 3 weeks into legion as it held no interest. Of course you can see we came back, well we each only opened up one acct instead of the two accts we both had.
I mean this character has a lot of nethershards that I can’t use.
