Freaking out! My Etsy Shop is closed

I woke up this morning to an email from Etsy Support that says:

I go to my shop and sure enough, it's NOT THERE!

I have emailed them twice but all I got was an auto reply saying someone will reply within 24 hours. I'm losing sales and customers while my shop is down.

I am wondering if it is possible for a shop to be hacked into, and some strange person deactivated my shop.

Advice anyone?
