Account Hacked

This is urgent.

My account was hacked and it appears someone bought a bunch of Nitros? I'm new to Discord so not sure how it happened or why they would do this. I am a student and this hack has costed be $1037.33. My entire spending account. This was for rent/bills/food. 

I have emailed support@discordapp.com and so far there has been no reply at all in almost 24 hours. Disappointing there's not even a hotline to phone about urgent matters.
