Absa Credit card complaint

I am currently banking with Absa Bank and my ID number is ***. I have a credit card with Absa of which I last used +- five years ago. My card was ****** with my purse some years back and I reported it to Absa, and also requested that they block it. I never collected the replacement card to avoid using the account again. I was contacted by Absa for a credit card limit increase, but I declined. I noticed that I am paying instalments monthly but the money doesn't go down, then I decided to go to The Grove Mall branch for enquiries. When I arrived there they told me that I'm also paying for a Credit card insurance that I did not sign for and nobody informed me about. I requested them to cancel the insurance as I had nothing to do with it. Again I noticed that the insurance is not stopped, and the credit card limit was increased. I did not concent to both. I had no agreement with the bank for both. I also lodged a complaint with Absa for investigation purposes, and I was told that I will be contacted. Until today I didn't receive any call regarding that. I would like to request the bank to refund me the insurance contributions since commencement date. I would also like them to cancel the insurance, I also completed the form in the bank regarding the cancellation. I want Absa to reduce the credit card limit also, I will let them know should I change my mind.
