Absa ***** department is a *****

I am utterly disgusted with the service I am receiving from the ABSA ***** department. I was informed that the turnaround time for a case is 5 business days after they've received required information, The said information was sent on 28 February 2024. Everytime I phone the call centre I'm told that the investigator will contact me, but she never does. And each time the matter is being escalated to the line manager and still no response. Yesterday I phoned again and I was told that the investigator is on leave till 8 April 2024 and the matter is being escalated to the manager again. We are on 28 March 2024 which is a month since I've submitted the requested documentation and yet no word or response from absa.
