Why are you taking my money?

Absa has been deducting a R23 from my account for months now for credit life insurance and I neither have a credit card nor overdraft with them. When I enquired I'd be told they will investigate and no one would come back to me. Today I called and the lady told me to hold and agyet holding for about 10min she dropped the call. I called again and the next consultant can't tell me what it was for he thinks it was for my vehicle finance which I cancelled in January and apparently they are keeping it for me for some death insurance thing that was never discussed with me. Absa I want my money back. My experience with this bank had been hell since my days as an employee there but I couldn't complain because I was on the payroll. The fact that I have to spend 30min on the phone only to get a shady answer is so annoying.
