Pathetic Service

I took an insurance for my device on the 22 February 2020. Again on the 05/03/2020 another agent from Vodacom phoned me for insuring my device I told him that my device is already insured, According to him the insurance policy that I took on the 22nd of February 2020 was not activated of which I was going to pay R63.00. I let him proceed but he never explained to me that I will pay R85, I assumed that it will be R63. I phoned Vodacom customer service with no help.
