Fix Meta Ads Billing Issue

I need an experienced Meta (Facebook) ads specialist to step into my current Ads Manager account and sort out a persistent billing and payment problem that is preventing my campaigns from running. The account itself is active, campaigns are built, and the pixel is already firing—yet every attempt to process charges fails and support tickets have gone unanswered. Your task is to diagnose why the billing section is rejecting or stalling payments, implement the correct fix (whether it involves payment-method verification, currency settings, business manager permissions, or Meta support escalation), and confirm that ads can resume spending normally. Deliverables: • Clear identification of the root cause. • Corrected billing setup or successful escalation with Meta support. • A brief hand-over note outlining steps taken and how to avoid similar issues in future. Once you finish, I should be able to add funds or let Facebook auto-bill without errors and see ads delivering again within the same day.
