Julie here from Shopify Support.
I can definitely appreciate the stress that comes with having your store become inactive. In any account-related situation, our team will reach out to the account owner via email with further information. Did you happen to receive an email about this?
If so, it's recommended that you respond to that email if you have any questions. Your response will go directly into the inbox of the team who is handling this matter and they will be able to provide some insight.
If you didn't receive an email about this, then you'll need to contact our live Support team directly. Unlike here in the Community Forums, our live Support team will be able to authenticate your account, view your account details, and offer assistance. You can schedule a callback or reach out via live chat through our Help Center here.
I hope this helps!
