Hey there, @wozayonline
Bo here from Shopify Support!
I am sorry to hear that you have been encountering this problem. It sounds like your stores have been shut down automatically as soon as a credit card has been added. In these cases, it is best to reach out to our Support team so they can take a look into this for you. I would be happy to do so. I will be reaching out via email, as soon as you respond to the said email I will be able to escalate this to our accounts team to investigate.
I look forward to hearing from you,
Thank you for getting back to me. I have taken this to email, all further correspondents will be via email.
All the Best,
