Unauthorised Debit order

I have had a loan with capitec bank since 2017.have been paying for it every months until January I missed payment due to financial constraints I called to make arrangement for February of R1000 instead of R1773 which is my installment..then they kept on calling me and massaging me stating my loan is in areas for R2567.94.on the 12 03 2020 I called to make arrangement for payment on the 13.03.2020 for a once off debit order of 2567.94 I was advised to pay at the branch if the debit order didn't go off..as agreed I went to the bank to pay R2570 on the 13.03.2020. On the 18 03 2020 I called to confirm if my loan was up-to-date and I was re assure that my account is uptodate that the debit order that is active is only my nomarl installment. then in the 20 03 2020 a debit order of R1814 and R2567.94 went off my account I then called the contact center who then confirmed than my loan was in advance with R2576.94 so I asked for a reversal as this was not the agreement and I was told it will be done in an hour..48 hours later money was not reversed so I decided to call my bank to reverse the debit order of R2567.94 today I'm getting an SMS stating I still ou R2567.94 how the hell do I owe money I paid at the capitec branch.the money I reversed was not supposed to be debited as I have paid already.. I'm very disappointed with the service received.
