Vodacom cancelled my insurance without my consent

I took my cellphone in for repairs, I then got a quote from vodacom to fix the phone. I was then informed that I do not have insurance. I called vodacom insurance who told me that my insurance was cancelled on the 10th of October 2023 without my knowledge. When vodacom insurance checked my account they picked up that they have not been deducting my insurance from by bank account since the end of August. I was informed that they will reactivate it once I do back payment and I must send them the quote to fix my phone, which clearly tells me that they can pick up it was error on their side. In August I sent a mail to update my insurance with the new phone I received, no one responded but instead I was called by vodacom and they confirmed telephonically that my vodacom insurance was updated. Why should I pay back payment when the insurance was cancelled without my consent, every single time I have to deal with vodacom repairs and insurance, it is an unpleasant experience
