ABSA made a mistake

So today i phoned capitec to ask if there is any debit order regarding Absa vehicle finance! The lady from capitec there is No notifications on my account that needs to go through. So i phone Absa Finance regarding this matter to tell me that i changed it to a cash deposit. I told the lady that i never changed it and even told the guy i spoke too, to keep the debit order. Since December 2018 i have been struggling with Absa to deduct the debit order in time, which they have not done and when i make a late payment they are very quickly to take extra money for they late payment. I think that this is totally unsatisfying customer service and that i must be reimbursed because the mistake was not on myside after all.
