Refund on overpayment of account

Morning <br> <br> I was under debt review and I settled my account early, NPDA made further payments into the account. I requested a refund for this amount and I could not be assisted as my account was under debt review. My debt counsellor then requested that the funds be transferred back to NPDA so it may be refunded back to me. 2 weeks later that request is yet to be attended by African Bank and the amount is still on the closed account.<br> <br> Please assist.<br> <br> Mveleli Ngxowa
