Hi, @najamsh .

Welcome to the Shopify Community!

Thanks for sharing your store URL and some additional context about the issue you’re experiencing.

To confirm, you’re unable to access your storefront as well as your Shopify admin? Could you check your inbox, spam or junk folder for any correspondence from our team? If you’re able to locate an email, I encourage you to reply directly to it for further clarification on your store’s unavailability.

If you’re not able to find an email, the next best step is to create a support request via the Shopify Help Center. Once your account is authenticated, our team will have access and be able to take a look at your admin/account settings and further investigate.

I’ll share the steps below on how to create a support request.

How to contact Shopify Support:

  • Head to the Shopify Help Center
  • Log into your account
  • Select a topic that best suits your query
  • On the following page, scroll down to Get Support to view our support contact options

If you have additional questions or need help accessing the help center, feel free to share them here.

I hope this helps!
