Statements for cancelled contract

I app**** for fiber while I was in Durban then I moved to Cape Town and started experiencing connection problems and I phoned them they ended up coming to my place try fix after a month of no connection. I have complained a lot of time of poor network. Eventually when I moved to Bellville I called them to cancel the contract as I opted for a different network due to *********** staff, poor service and poor network. They will tell you call back and when you call they say they cancelled. But every end of the month they send statement. When you call again they say we will call you back shortly which they never did. As for me I can pay for 2 network fiber providers which I don’t use the other. I pay Rain because I use it. When I have a problem I get assistance immediately. As for Vodacom you can send as many statements I ain’t paying for any of your bills. I’m actually wanting to port even my cellphone number to a different network. I don’t have their services in my house and not planning to use or recommend them for as far as I live.
