Party Problem

Hello everybody, first of all sorry if my english is not so good i want.
I did today like at 11 am a dungeon, before we finished it, a player leaved the group and somehow we couldn´t queue to find another player to help us, so we decided to leave the group. After this, i used my hearthstone to Dalaran and when everybody leaved the group, i was still in a group. I am still in a not existent group and i can´t join a queue, be invited to a group or invite someone to a group. I writed a ticket ingame for 3 hours ago but i become not help.

Thanks for reading,
Kaiserr.

type this in chat or copy+paste mine:

/script LeaveParty()

Thanks man, it worked.
