A late charge will be assessed on any customer bill which remains unpaid after the statement closing date.  This charge will be the greater of either $8 or an amount that equals 1.5% of the unpaid balance.  This charge will appear on the next bill.  You can make payments using direct bank debit, online, through mail, or in person at our corporate headquarters. Please note that a fee may apply for agent-assisted payments.
