A payment that was returned by your bank will be reversed. This is often referred to as a “bounced check” or NSF (Non-Sufficient Funds). The reversed payment could cause late fees to be applied to your account. An NSF fee of $20 will be charged to your account. The returned payment will still have to be paid. After two checks or online payments have been returned for non-sufficient funds, only certified funds will be accepted for that unit.
