Improper Sales Procedures

I purchased a car in Feb 2021, somehow an extended service plan, top up Plan and shortfall cover was added-these products were not explained to me and I did not receive adequate documentation on the amount, terms, etc. I figured out the issue in November 2021 and called Suzuki Bryanston, they told me to call Wesbank, Webank told me it is the dealership's issue as they sold the policies. I called Suzuki again and they referred me to the Innovation Group. I called the Innovation Group and got an email stating the cancellation has been sent. However, in January I was still paying for the policies and gain tried all three, only to be assisted by Wesbank who sent another cancellation query. It is now March 2022 and still spending large parts of my day on getting this cancelled. And I still do not have the policy terms from any one involved. This seems very much like untoward business procedures.
