Duty, Honor, Country quest is seriously bugged for me.

I no longer have the quest but I have not attended the dinner, I never received an item to attend the dinner like every one else that has done this quest.

after the cut scene when I was invited to dinner, it said quest completed and that was all. no new quest no item, no other story quests pop up for me. I HAVE NOTHING.

I have been trying to get a GM in game for the last 5 days and I finally got one today and he says post on here, I do and I get the same run around BS.

im lvl 20 cant get a mount because that's a stupid main line quest I cant progress for crap and I get no help from anyone in game that can help.

I cant drop the quest because I don't have it. I CANT RESET IT BECAUSE I DONT HAVE IT. all of my FC members all say I got it right away and walked right thru it. IM STUCK, getting mad and want this fixed. someone please stop giving me the run around and help me for once.
