Vodacom RSA is a ****mer

I took a data sim card contract about over 3 years ago. The contract was signed for 24 months. 24 months passed and I requested to cancel the contract and subscription. Vodacom has been giving me run around but never cancelled. I had discontinued using the service and no longer even have the sim card. Still I was later told to pay R2062.08 for it to be cancelled citing that I am in arrears. And I did ( proof attached) I then called and ask for cancellation again which I was told it will be effective end of the month I paid (October 25). To my surprise 5 months later I am getting invoices and instructions to pay again, and no cancellations is effective. There’s a subscription charge for R810 that I don’t know what is it for. I had never taken/subscribe to any product or service from Vodacom. Now I received a statement saying I am owing R1236,03 and I have no clue how it came about while I requested cancellation numerous times.
