Vodacom incompetance

As of May 2023 vodacom has been adding comprehensive insurance onto my account without my request. From May until November 2023 I received constant calls harrasing me to pay up my account, and certain services on my phone was suspended due to the account being in arrears dispite the fact that they admitted that it was a mistake ftom them. I contacted them 3 times a week and the answer was always they are fixing the problem and then I would not hear from them again. Only when I reported them on Hello Peter would I get responce back from them. It took till November when they finally credited my account with an amount of just under R1800.00 . However, on my New November statement the insurance was again added, When I contacted them the excuse was that they probably forgot to cancel the insurance on the system when they credited me, but that they will rectify immediately. I even received an sms stating that the insurance has been cancelled, so I assumed that the problem will again be rectified. Again I started receiving calls for my account not settled in full, but as it os a mistake from vodacom I will not pay that part of my bill and only pay the amount for the services I dis in fact request. I received my statement for December this week, not only was I not credited for November, but also insurance was again added. This brings the total up to R616.00 that they have billed me for incorrectly. Vodacom you are absolutly useless
