Credit Card payment not credited

I have made a payment for goods ordered from my FNB account. The company providing the service/goods could not supply and as my ABSA CC was overdue I requested from the company to credit the funds back to me, by returning the funds to my ABSA CC. My thinking was that, this saved me the time and effort to have to pay the funds again from my FNB account. The company returning my payment, put the reference as \reversal of payment\" ABSA then viewed this money as a reversal of a payment done from my ABSA CC, however, the initial payment was from my FNB, thus, the money was not a ABSA CC reversal, but a refund for funds from my FNB acc. ABSA has now contacted me 11 times requesting a payment for my CC. I have informed them that the reversal was funds from FNB, they still refuse or do not know how to do it. I have lodged a complaint on 1 February 2016 with a promise of 3 days turnaround, still no feedback. But they keep contacting me for payment. I have lodged a complaint with the ombud, even they did not answer me. Please help"
