Shoddy service

Having had money transferred from my account with no communication or authorization I spoke to a private assist agent who was outstanding, looked into to situation and call back to apologize and to confirm that a private banker would be in contact with me to rectify and confirm same in writing. It is now a week later and neither my wife or myself have had any communication. Today a I called once again to have the first private assist agent disconnect my call and on 2 further attempts I have been unable to speak to a banker Not what is expected for a private banker nor ABSA bank
