Facebook Security Check Preventing Login

Hi,

My wife's Facebook account has been disabled, and she can't get through the Security Check due to OLD phone numbers listed that she doesn't have access to anymore. It's extremely frustrating as Facebook support is practically impossible to reach. We've managed to submit a ticket but have had no luck with any type of response. We have a business on Marketplace so our pending balance is just sitting there along with orders that we're not able to fulfill. Does anyone have any experience resolving this issue?
