Why is my newly registered website showing as unavailable?

I register a shopify store a week ago. Customized the theme,set up payment & shipping, pick a lot products to sell (this takes a lot hours of work) and I’m impressed & decided to go Basic Plan $19. After I’ve paid then this message showing

"is currently unavailable."

What’s really going on? Payment was charged but I was not able to see my business running.

So, Please help.

My ticket number is 31723428.

thank you

If your website is down, it can be due to an error with your DNS settings, hosting provider, or web applications. An offline site can also be the result of security issues due to hackers attempting to penetrate your site with malicious code or DDoS attacks.
