Unacceptable Service

I reported a case with the ***** department at Absa Bank on the 12th of October, the consultant advised that the investigator (Edward Mohajane) will contact me in 48hrs and the case will be resolved in 21 days. I called on the 1st of November as I never received any feedback, but was told the investigator will contact me. I've been calling every week and everytime they say he's on a call and will call me back. An email was sent to the manager (Matilda Sibande) and yet still no feedback was received. It's going to be 2 months soon and I must say I'm very disappointed with the service from the ***** department at Absa and due to their procrastination on this case, I'll never get my money back
