Finrite Administrators on Vodacom Cellphone Insurance

I called Finrite on the 1st July 2020 and spoke to Thuto Mashigo regarding the cancellation of my cellphone insurance and he confirmed that it was successfully canceled and even sent an email confirming that. Now in August I received my vodacom invoice which they billed me for the same cellphone insurance that I canceled on the 1st July 2020 and when I called Finrite on the 5th August 2020 they told me a story that the vodacom billing system is not picking up the cancellation on their side and that they will re-cancel it and confirmed at the end of the call that it was canceled. Now September billing also comes with the cellphone insurance showing on my vodacom invoice and they tell me that I have to pay for the insurance in order for them to cancel, like how crazy is that? It’s not my fault that their system is ***********, I just want that insurance canceled as in yesterday.
