Billing query not resolved

I requested standard bank to reverse a debit order of Netstar for R144 in January and this was done at the Alberton branch.In February I went to the Eastgate branch to reverse the same debit order.A consultant helped with by saying he will reverse it permanently as long as Netstar will debit same amount the following month.This was done at a cost of R45 and the reversal for February was also charged.The one in January was not charged.In March the same debit order has gone through despite me paying a fee of R45 on assuarance by standard bank that this debit order will not go through if the details are still the same.Nothing has changed in terms of Netstar details,account number and debit amount is still the same.
