Pathetic business banking services

If I could score this bank a 0 I would, I have been trying for over 3 weeks to place a notice on my Business Notice account, I have explained to my banker Mr. Nkomo over and over again that it is not allowing me to do it online, his response was it should, or call the call center for further assistance. Firstly if I have to call a call center agent what is the purpose of having a banker assigned to your account? secondly i called the call center and they advised me to speak to my banker, so ultimately no one at ABSA can assist me. The worse part is I have copied Action line on all the emails and did not even get a single response from them. so if you cant complain to the complaints department who do you go to, to have your queries resolved?
