Old core character - Unable to unlock quests

Hi,

I'm not able to complete all quest chains in Icecrown because zones do not phase. I know there is a lot a ppl reporting this kind of issues.

I have recently completed all quests in the zone before Orgrim's Hammer (if I remember correctly I had progressed after that some time ago but some reset took place?), I have no more quests available, got all dailies and drop item quests...

I have a lot of similar issues like this, for example I'm not able to unlock brunnhildar village dailies, commander kreega underneath ICC is phased out, etc...

Has anyone deal with this before successfully?

Is there anyway to request GM support on this?

Thanks
