Nonsensical incompetency

My wife and I bought a house in 2020 and took additional assurance on our lives, which was not compulsary. We called on the 1st to cancell the assurance, we were told that we have to write a letter, yesterday 06 July, my husband called again as we were still waiting for the consultant get back to us with an email address that we need use to submit the letter of cancellation. To our suprise, the person he spoke did not even bother to get into the system to check anything, she just told him that we need to have a life cover that is of the same value as our house and on top of that, it needs to have the same benefits as their assurance. Why is that the case, because we took the policy after the lian was approved and it was not on condition that we take an assurance aginst our lives??? Standard bank consultants are ***********, we are still waiting for both women to get back to us. They just respond to you for the sake of answering, thay do not know their products. The policy was our choice and we can cancell it at any point we wish to, it is amazing that we have to go from pillar to post to cancell, but when we took it, it was just over the phone. I wish we could cancell all the products we have with them.
