Worst Service Ever

On the 2nd of December I called Vodacom Insurance to cancel my insurance which was ending on the 15 Dec 2020 and i was advised that it will be done. I follow up on the 23rd Dec 2020 still escalated but it will be done. I called back again on 31 Dec 2020 , it will be sorted please be patient. I called again in January 2021 on the 8th . It was not done but this time it will be actioned . I then got an SMS that my query was resolved but on the 1st of Feb 2021 I still got the package i cancelled . I send an email to the enquiry department and they called me saying it has been escalated. Another SMS came through that the matter has been resolved but now I am shocked today the 1st of March , they still send me the package again which I tried so many times to cancel. This is it , right now i will reverse the debit if it comes off my account as they did not get my permission for this transaction. I am disgusted on how they handle customer complaints and how they want to benefit with one expense. I told them to cancel my contract but they still don't want to . This is the most worst service I have ever encounter .
