Vodacom insurance

I was renewing my cellphone contract with vodacom in June 2020 I was paying cellphone insurance of R60. 00 then so when I renewed the contract I took Huawei and it was also covered to my surprise the insurance is now R300. 00 I called vodacom contact center to cancel and they gave me insurance number (***).

I called and spoke to a number of consultants in August 2020 canceling the insurance but it's still not canceled the last consultant I spoke to is Sedumedi on the insurance department. They still debiting and I don't afford this insurance I am even thinking of changing my bank account
