Poor service ABSA

Early this month April I spoke to a lady by the name of Renuka Ramsaroop from ABSA in connection with my vehicle finance account. There was a debit order that did not go through which I did explain to her what had happened. Then she made an arrangement that for that debit that did not go through I pay it within two months R1300 via eft as she said she could not set a debit order for that arrangement and the normal debit order will run normally. This morning I saw on my statement that two debit orders have gone through for my vehicle R2474,41 and R2473,91 NOT as arranged. I need that one debit to be reversed or the difference from the R1300 because I have other debit orders that need to go through. I'm so irate and this service is not acceptable
