Disgusting lack of service

For the past five weeks I have been trying to get a resolution from Vodacom of an amount on my account which I do not owe.I keep getting told 'it will be escalated'. This morning I received an SMS threatening cut off of my service if I don't pay this amount, which is for insurance back in April 2021 that I did NOT request. The next step for me is the Telecommunications Ombudsman..I am completely disgusted with the way is problem has literally been ignored...
