Wesbank adding fees to my account

I have called WESBANK twice in January. I provided my insurance details and the consultant confirmed that they requested a cancellation to not add any cover to my policy. On the 07/02/2022 I received a letter to confirm that my premium will increase by R497 due to insurance cover being on added. I called the call centre today again and the consultant told me she would escalate the query but I should call ***to follow up directly with the insurance department. After spending what felt half my work day on hold , I went to the FNB branch and spend the second half of my day on hold at the branch. . Please assist with cancelling any insurance added to my account. I emailed *** but received a generic response with no reference to follow up on my query
