Vodacom - Service Cancelled but still charged!

I must say that I cannot believe I am having to write this again. I thought that this issue was put to bed after my previous experiences. I seemingly cancelled my Vodacom insurance in July 2020 after hours of being on hold, only to find out that it wasnt actually cancelled and I have been paying R200 a month for Insurance I cancelled! why do we have to continuously encounter incompetence in this industry. I expect to be refunded! I am now dreading the fight again to find someone who can actually do this properly!
