Debit order processed twice for a settled account

At the end of November, my bakkie was ******. The account was settled in full in the middle of December by my insurer. However at the end of December a debit order was processed. After much aggro and fighting, it was established that the settlement from the insurer was never allocated properly. It took me 5 days and much unhappiness to get my refund and finalise the account.<br> <br> And now, to really get my back up, I have found that yet another debit order was processed again at the end of January, after the account has been settled for almost two months!! I really do not have the time or inclination to go through this whole process of following up and requesting a refund - this service is diabolical and I want the money refunded immediately.
