I find myself in the same situation as Venere stated. I just completed the 1st PVP set and got the wrong one because of that. So I am awaing an answer from NCSOFT due their mistake as you can't pretend to let players after all having to start again when is clearly not our fault.
I just hope NCSOFT sort this out and replace the set as it is not fair to having to farm again for 3 weeks to be the same way as I am now, plus spend again on enchanting which is crap too.
