My online Banking has been suspended for 20 days

On the 6th January 18, I missed a call from Absa ***** and got a message that was alerting me of a ***** in my account, I called them and I was told that there was a sim swap attempt and someone logged on my online banking but from a different device and that they attempted a transaction but declined a surecheck. However the service assistant said she will declare it as ***** and suspend my internet banking and allocate it for investigation. A week after this incident I called absa ***** line trying to get an update on my account's investigation but no ***** case was initiated, another service assistant told that she will open a ***** case and allocate to someone that was suppose to contact me for investigation. Yesterday I called the *****line and assistant put me on hold until the phone when back to the main menu/general enquiries line as she was looking into my account, so was assisted because the phone went off, I hoped that she will contact me back but no luck. I called again today same thing happened i was on hold for so long that the phone went to general enquiries menu and off again. Its month end, I understand the risk associated with my internet banking being hacked but i will never understand why is it going to take them so long to communicate with me i'm so inconvenienced I am stuck can't do anything. Atleast to get progress status of the investigations the reference is **********
