Holding for 55 minutes

I recently did a sim swap since then I have not been able to do internet banking. I have been trying to call the Absa Internet Banking service desk but I have been placed on hold for more than 55 minutes with no response. I attempted three days in a row and was placed on hold with no response or service for 34 minutes, 47 minutes and 23 minutes. All I need is for Absa to activate my sim.
