ABSA bad service

On the 01st of October i was phoned by your head office regarding a stop order that should have bounced because of insufficient funds but absa put the stop order thru and let the acc go into a minus. I informed the absa employee that the branch was closed and the stop order should be reversed because the future payment was not yet canceled and it should not have been able to go thru the account seeing that there is no overdraft or funds available. She assured me that the stop order will be reversed but it would have a negative affect on my account on which i asked her to continue. Its now almost 2 weeks later and the stop order has still not been reversed regardless of the fact that the account is now in a arrears and there should not be a overdraft on the acc.
