returned Debit order fee

I was hospitalised during my debit order days and I couldn't manage my funds, I received and sms from my Bank that the debit order has reversed. when I was discharged and wanted to call Telkom to get banking details to do EFT, I received a statement via email advising me that I will be debited +-R600 which included R200.74 for the returned debit order. such *******, fee that is even higher than my instalment, I called the call centre and spoke Nhlakanipho and requested to dispute this fee and wanted to speak to manager and they promised to call me back till today no call back.

DAY LIGHT ******* FROM TELKOM!
