I'm so sorry to hear this, I can understand the frustration here. Usually, I would reach out to the email account linked here to your Community profile to authenticate you as the store owner first before I can investigate why your store may be unavailable. But I can see when I was creating the email, you've already reached out via chat! I can see this is already being looked after for you and our higher support team are actively working on resolving this for you. They should reply to you within on that same support ticket with any updates.
Thank you for your patience, the team here are doing their best for you so I'm sure this will be resolved soon!
