That's breaking your contract... and is frowned upon.
While we know that things happen, you should always give us a call so we can review your account. Keep in mind, if your payment doesn’t clear, our Payment Services department will contact you to arrange payment. If your payment is returned you’ll be charged an NSF fee and could be charged additional interest if you don't make the payment right away.
