Double deduction of Bond payment

We had a debit order from my husbands acc then asked to change it to stop order (direct from salary). We requested this from November 2014, however the bank did not stop the debit order and therefore we were paying double bond instalements which we then had to query every month to have the 1 payment reversed, which took app 2-3 working days. This then continued till April 2015. We then requested a reduction of payment to half our bond amount for 3 months due to inconvenience as we had unpaid debits because double deductions. The arrangement has now ended and once again we have had a double deduction from my husbands account. This is not acceptable and I want somebody to contact me as i am tired of contacting the bank. <br> <br> Please sort out this mess urgently as we are incurring unbudgeted expense due to the double deductions and unpaid debits reflects badly on our credit rating.<br> <br> Mrs Mabuya
