Billing - Debit Order

I contacted the Green Light and Group Scheme department at Old Mutual in December to inquire why my debit order for November wasn't deducted. I was told that I had to give authorization first. I then requested for my debit order to go off on the 18th of December as I was receiving my salary that date and they should deduct for the month of November as well. I then advised the debit order date should be on the 28th of each month from January 2016. I received my bank statement and I am being charged R430 in bank charges for Old Mutual debit orders that was rejected. I contact Group Schemes and the consultant made it seem that it was my fault and that he can't find anything on their system regarding my request. Which means the person I spoke to never did anything regarding my request. I need my money back.
