Haha, good luck with that! Don't mean to say it in a bad way at all, but all these big exchanges have a really bad reputation for support, especially for the minnows like I'm pretty sure you are.

The key is to keep trying, but always be polite, and don't spam/flood. Just a polite reminder every few days on all channels. Eventually, that will work. But don't be annoying or rude, remember these are also people and they will rather help a polite customer than an annoying brat.

Keep your ticket to one number also, don't keep opening new ones.
