Admin Error Horror

What a horrible experience having my second car financed by ABSA vehicle finance. I am now probably having a bad paying record on my credit profile i should have stuck with Wesbank. On the 28th May 2018 my first instalment was meant to go off for my vehicle it never went through, a week later i got a call from the collections Department at ABSA i was bamboozled by this call i then told the guy to please repeat the details of my account cause its impossible for them to have not found the funds in my account on the 28th. That's when we discovered that the administrator captured my banking details incorrectly. I Spoke to a lady with the last name, Govender and she said she will then make a note and will set the debit to order go through on the 08th, I was asked to send an email with my bank statement and ID copy to ********** and a consultant will assist me in correcting the banking details and the report that goes to ITC on one's credit profile and paying behaviour as this was now my paramount concern because I am currently looking for a house. I Spoke to a lady named Latoya Woods who was going to assist in this regard, she advised that I make a payment I told her the previous lady had said she made a note for the 08th and the system will have the correct details. I was happy with the arrangement after a few days nothing got debited I called and explained the situation to the collections person Tshepo I think his name was from there he was going to escalate, I also got a calls in-between I kept reciting the same story can they check notes against my name. Its been back and forth I still haven't gotten a resolution or a report that they've retracted and rectified my paying behaviour at ICT. From this month the 28th June the debit order did go through which means my details were corrected however I am still being called about they May instalment which I do not have now and i cannot make arrangements to pay more on my monthly installment, I've explained I am still waiting for a response on how this situation will be remedied honestly if it means they add an extra month to my contract to recover the May payment I'm fine with that, however, I am not happy at all how this case was handled. I need my name cleared cause I'm not a late payer.
