No Feedback on complaint - Lack of professionalism

I would just like to share my utmost disappointment in ABSA bank. I've requested ABSA to stop all debit order and close my account in March 2018, however it seems as if they did not close my account as requested. They've only stopped the debit orders after numerous emails and calls back and forth and I've incurred bank charges due to debit order that returned. I have informed them that I will not be kept liable for those charges as I've requested them to close and stop all debit order. I was assisted by a lady by the name of Vanessa Crowe who at times ignored my emails and phone calls I was only assisted after a month when i complaint again and requested that I do not want to be assisted by Vanessa as she lack professionalism. I was advised by a senior manager that the debit orders will be stopped and the account will be closed. After a few month I've received an sms stating that I owe the bank and that the account cannot be closed as i first need to pay the charges that I've incurred. I've questioned this and I was advised that someone will get back to me with feedback which was not done. About a month ago I received another sms stating that my account has been handed over as i still owe the bank R1633.00. My question is, how can i owe the bank after I've requested for the debit orders to be stopped (before the initial deduction date) and for the account to be closed after numerous complaints. I've sent through another email with regards to the above and to date i have not received any feedback from ABSA bank. Once again your Services are pathetic and i am relieved that I am not longer a customer with ABSA bank.
