Very disappointing ABSA customer service,

It's really frustrating to deal with *********** and unprofessional people that you supposed to trust as far as your money is concerned. I have a Cheque account with ABSA - an authorised debit order came through without even receiving a DebiCheck mandate, how does Absa allow debit orders without DebiCheck mandate, I addressed the matter with them i was told a consultant is assigned by the name of Tumiso Shongwane to look into the matter, i have never heard from Tumiso Shongwane the only thing i was getting is automated messages that says - He is busy investigating my complain and will give feedback on the 29th Oct, come the date - it changes to 30th Oct, come the date nothing from him and when following up get same message saying still investigation will give feedback on the 1st Nov, before the end of the same day i received this message another message comes through saying the same story about investigating but now with the different feedback date which is now the 4th Nov. I'm sick and tired of these games that Absa is playing with me because really I'm not interested - as a matter of fact i am disgusted. All i want is this unauthorised debit order reversed - or else I'm closing this cheque account and other accounts that i have with them and take my business else where where i will be treated with respect no how small my money is.
