Hi @Richbelief
Sorry you're experiencing these problems,
Shopify have created a detailed post on this here: https://community.shopify.com/c/Shopify-Discussion/FAQ-Why-is-my-Store-Unavailable/m-p/1077560#M2284...
It is best if you get in contact with Shopify directly, as they have more than likely flagged something on your store that needs investigating, it is more than likely nothing, but they will just need to check. They do say it takes about 3 days to resolve the issue after the support ticket has been raised though, so be prepared to wait!
