Raid/Quests/Support Not Working

So here’s the deal. I’m playing on the EU client despite being in the United States. I don’t know if that is causing my problems.

At the moment, these are my current problems.

I cannot use the in-game support function which includes being unable to submit bugs which is just amazing. The support menu just spins whenever I try to open it.

I cannot complete the zone achievement for Badlands as one of the Deathwing quests is bugged. I cannot click on the cloud to find Deathwing.

I cannot complete the Naxxramas raid as Kel’thuzad resets every thirty seconds or so no matter what I do.

I’ve tried asking in trade chat but I seem to have picked a dead server. I know that the global channels are working for me. It’s just that there are no responses.

The funny thing is that I’m progressing through each expansion in chronological order. I figured I would report any bugs that I found along the way. I haven’t been able to report anything.
