Unauthorised Debit Orders

In December the bank decided not to communicate their intention to debit my account earlier which later resulted in service charges being incurred in my capacity. For the past two months I have been trying to have Samuel and the Nedbank group reverse and pay or my service charges to no avail. I have had numerous emails back and forth with Samuel and still have not had any solution even with proof from the ABSA account they debited without any authority from me. <br> <br> I am looking for the reversal and deposit of my my funds as I have been requesting all this time.
