Toolset Delivery Quest not working

[Metalord]

So I recently tried doing this quest from Wenglawks Kkeak in Kael Drakkel on my lvl 51 War. I receive the voucher for tools from Wenglawks, and am told to take it to Kellek Fellhammer in the next room to get the tools. When I give the voucher to Kellek I get nothing in return.
