unhappiness about payment made and not reflecting

I had a credit card with std bank. It got handed over to nds. In Jan 2016 I settled a bal at Somerset branch. I contacted nds n informed them about settlement. They informed me that my account has been hand ove to mbd. I ve been taken from pillar to post. Mbd says it's n reflecting on their side. This is frustrating a it should be something that they can sort without inconveniencing anyone. Settlement wa supposed to be R774.03 a I paid more than that. I got the proof of this payment. Sasha from Somerset branch ha mad contacts with parties an I have not been helped until today. I therefore request hello Peter to intervene in thi regard. Am reachable on ***.
