Poor service by Absa ***** department

On 5th May 2023 I opened a ***** case with Absa bank because money disappeared from my account, and I was given the following case number: ASZA-2***3. I was told that the investigation would be done in 10-15 working (25 May 2023). I never got an update from absa and I have been calling them since 25 May 2023 and every time the absa ***** department keep on telling me that the investigator will contact me but she never does. I am very disappointed with poor service from absa bank especially since this was supposed to be finalized a long time ago.
