UNAUTHORISED DEBIT ORDERS

After making arrangements and requesting debit orders to be cancelled, which by the way I have on record, ABSA still sells the account the attorneys and debits my account. The latest debit of R11576.36 went of today - how am I supposed to pay my other debt, buy food, pay rent etc? I have it on record to cancel the debit - you dont even have a mandate to debit the amount you did. Every month I have to go through this and reverse the debits. What the point of making arrangements? I cannot wait to get rid of this bank and tell the whole world what disgusting business you serve!!! you were no help at all during trying times and I will not do buiness with you ever again
