ABSA has a broken system which is not fixed

My idirect policy was posted to an address that was never provided to Absa. Upon calling to request an amendment, I was informed that the system Is broken and they cannot amend the details. Personal information is now being sent to places it should not be going to. When asked how would I know that the system is fixed I was informed that I will get a policy document, which will then go to the address that was never provided to Absa. The consultant did not even make a note on the system indicating that they have incorrect information.
