Mate, forget "will it be back" - the real question is how fast you can get it back before your pipeline bleeds out.
Blocking the cards was the right first move, but that ad account is sitting in a suspended or compromised state right now. Meta's recovery queue for hacked accounts is a black hole - anywhere from 3 days to 3 weeks, depending on how many hoops you jump through.
What actually moves the needle: submit the business verification and ID docs immediately, then open a chat support ticket. Don't rely on the help centre forms - they're garbage. If you've got a Meta rep, lean on them hard.
Pro tip: while you wait, spin up a fresh ad account on a clean BM (different payment method, different IP). Don't let your activation rate tank. A hacked account without a recovery timeline is just dead inventory.
