Broken System and setup for failure.

Last Year I closed My Standard bank cheque account. I went into the bank and the banker closed the account and paid out what was left. Now after more than a year I get calls from people saying I still owe 3,000. After enquiring this with the bank they said the account did not close as there was debit orders. I requested statements and these debit orders are standard bank account fees and so on that kept going off, no external debit orders. This indicates the account was never closed properly. So in order to close an account they draw out everything to get it to 0, then month later deduct a bunch of **** and puts you in arrears, don't call you immediately. Months later they call you aw sir you owe us 3000 rand. ***. I'm not paying that as I went into the bank to close that account at the Sandridge branch in Midrand via the banker. Please fix this mess, your other mess is also impacting me negatively, so glad I moved to another bank and the reason for moving was because you cant do banking properly and setup people to default. I am SO SO SO MAD.
