ABSA BAD ACCOUNTING

My wife made an arrangement in November 2023 to pay off an account with them. She agreed to pay R600.00 per month. This has been paid EVERY month since then but for some reason ABSA have not reflected these payments since January 2024 on her account Suddenly they have found the February payment after my wife sent to them the proof of payment for the missing 5 months. They handed this matter over to Shackleton Credit Management (Pty) Ltd. who handed it to Lynn & Main Attorneys for collection. All the attorneys have done is to threaten my wife and insisting on payment of the full outstanding balance even though the collection agency had previously agreed that an arrangement could be made to pay off the outstanding amount. If ABSA had sent out regular statements it would have been seen that the payments were not reflected and investigation been done earlier as to what was happening with the payments. The attorneys just ignore the payments made and not reflected and just want their money! What they are saying is that the full outstanding amount must be paid now and if my wife can get the refunds of the payments made, then good for her, but they are not concerned about this. What about the overcharged interest? It is about time that ABSA admitted that they have accounting errors and apologised and corrected their errors. The attorneys, collection agents and ABSA are all bullies and NOT prepared to listen and correct their errors.
