Hi, we changed the credit card and after a day they blocked our account. After the review we got the following message.
Thanks for contacting Facebook.
We were unable to verify your payment method.
To protect our users, we can’t confidently re-enable your payments account at this time. Please note, we take many factors into consideration when disabling payments, including spend history, ad characteristics and contradictory account information.
