To get in touch with Shopify support:
Their is no place to leave a call back number!!!! I spent all day yesterday on a chat and got no where. I'm trying to open my store but i have some problems and cannot find a way to have them call me. Also when it says do you have a shopify store and i say yes it tells me Sorry this shop is currently unavalable. Im so mad right now.
Did you create your store with a unique email address? I only ask because when we did that, we faced the same issue, and the quick resolution (self resolved) was to create the account with our @ gmail.com email and it worked just fine.
