Insurance just takes money

On the 6th of March 2019 I did an upgrade. I also changed my insurance portfolio from tablet insurance to cell phone insurance to the value of my new device. Subsequently I have been charged for 2 insurances. Tablet insurance and cell phone insurance. I phoned Vodacom who told me to contact Finrite, which I did. I emailed them but never received a reply. I the phoned Finrite and they said they would resolve this issue. To date nothing has been done and I'm still being charged for two insurances. I requested that the tablet insurance be stopped and that I be re-imbersed for charges I did not request. No one seems to bothered and it seems such a schlep for them to do anything regarding this matter. They all to quickly sign a person up but when it comes to problems no one seems to want to assist. This is unacceptable for this is not what I requested and I don't know why I should be billed for something I have cancelled.
