Absa and partners refusing to take my money for out standing loans

We have 2 debt accounts with Absa. We financially immigrated 2 years ago and closed all our bank accounts. In this 2 years we have been struggling paying these 2 debt accounts. I mean struggling... We were hours on the phone with the bank and lawyers what to do and how to do it. We made a payment to one of the accounts and after 6ish months they still can't verify they received the payment. I have given up completely and will end up on the black list for the incompetence of ABSA and their partners. Can someone competent please contact us and help us finalizing this...
