Tired of ridiculous bank costs

My microsoft payment was scheduled to go off today, the 1st of April - I canceled it. Nedbank has been running a debit order since 26 March. I didnt have enough funds for the transaction at the time and till this moment they have run it 9 times!! @ R8.60 per failed transaction. I will be closing all my nedbank accounts after being a client for 7 years.
