Right, but, pay by wire to settle what Meta thinks is outstanding, and then initiate the chargeback process. At least during the pendency of that process, you’ll have that wire transfer documentation that seems to be the only thing Meta can comprehend, and you can (hopefully, fingers crossed, get back up and running).

I get that there’s a real risk here that you could wind up out another $40k at the end of the day and your problem still isn’t solved, but if losing access to the Meta market is as fundamental a risk to the business as I took away from the post, then it seems to me like job one is to ensure that the business survives and that the (admittedly unpleasant) process of getting trued-up on the $40k is exactly the kind of thing that your lawyer is for.
