If it doesn't debit within the next week or so you need to call them. Sooner or later they will figure out that a payment wasn't received this month and you will have a royal PITA (especially if you don't have detailed records/proof that the payment was submitted but they didn't process it). Let's say they don't discover it until this time next year. They're likely to drop 12 months worth of late fees on the account. Depending on how shitty the bank is they may also report it to the credit bureaus or even try to foreclose on you.
You could probably get all of that straightened out if it does happen, but wouldn't you rather just make a 10 minute phone call now?
