Vodacom pathetic service

Hi, I was allocated a R6,99 insurance on my profile which I did not authorized. Now I am having a bad credit record because this was not paid for a couple of months. I logged a dispute on the 15/06/2022,got a reference number and 46 min later on a call. Nothing at all was done. I called again today 05/07/2022 without any success, just being transferred from one department to another. I decided against my will to go and pay the outstanding balance and then to call *** to cancel this so called insurance, after a frustrated 51 min on a call again from one department to another I am now back to square one. VODACOM what else do I need to do to cancel this insurance and clear my credit record??????
