Over payment on debt and struggle to clear my name and be able to apply for any future credit

Good day, In 2009 I was placed under debt review On my VEHICLE the outstanding amount given by Absa, was R148 647.54(2009) The full amount was paid 15 November 2016, but Absa still want a amount of R1400

The outstanding amount on my CREDIT CARD was (according to COD amount from Absa) was R3012.27. the amount was fully paid in March 2015. However an over payment on part of the debt counselors in the amount of R 952.29 was made, and Absa still want a amount of +-R700??

On my PERSONAL LOAN Absa gave us a COD amount of R30 358.61 and was paid in June 2016....however ,payments was made in the amount of R R41 275.48 (over payment on the debt collectors side with R10 916.87) Absa paid back an amount of R222, and according to them they don't owe me anything!

Absa to respond with explanation as to why full over paid amount was not refunded
