We haven't sold any items using this account for the last 3–4 years and it was on the basic plan. We have a different account selling entirely different products. However, two days ago, I received an email from Amazon saying our current active account will be deactivated, apparently because this old account was deactivated due to missing credit card information.

I’ve now submitted the required documents. Does anyone know how long the approval process typically takes to reinstate a deactivated account?
