Poor service from Capitec

Hello Peter Two months ago the company I used to work for went under liquidation. I brought all necessary documents to Capitec Bank to make the necessary arrangements for payment due to the fact that I'm currently unemployed. The arrangement which was agreed on was that I pay a minimum of R25 on my loan. Today (10/04/19) I received my first UIF payout and they still deducted the full amount even after I made it my duty to come in and make an arrangement with them. I went back to them to state my complaint and I was told that they have nothing on their system but I received a letter that confirm the arrangement that was made between us. The consultant just told me there's nothing they can do for me after I told them that they deducted the full amount.
