There is an error with the payment method. It seems as though the system have made changes to the site, therefore the deposit of $21 is not deducted from the $70. Whenever i made the attempt to pay the balance of which is $49, the system is still showing that i owed $70. Please fix the error so that i can pay the balance and get my assignment. I just got out of the hospital today so sorry for the delay. Thank you!
