Debit order issues

My account had money during the last week of April and May, and the EduLoan statement reflected that they did debit my account for the student loan. I made a call to their call centre to ask if my account has been indeed debited and a Rochelle confirmed that a payment had been received from my bank.<br> <br> I downloaded my statement today to find out that they did not debit my account even though I had money on 1 May and now they are charging me money for debit order unpaid. A call to a call centre agent did not help as she told me that even though there was an error on their system, they will still charge me fees for unpaid debit orders and interest on outstanding installment. <br> <br> Your service suck!!!!
