Money taken and wont refund

I had a debit order for loan by Capitec on a Absa account. Went on debt review and Capitec just switched the debitorder for absa to Capitec without any warning. Now they dont want to refund the money although they have received documents stating I was under debt review. I wont ever do business with Capitec again. The people from the Branch in Postmasburg has the ****iest attitudes. No one wants to help me regarding this matter as it was my last money and now the just dont care, why did I apply for debt review in the first place?
