The nightmare continues

I have just received my Vodacom statement which shows that my home internet is still being billed and for some reason now it's even close to 1k. I had thought that this nightmare ended when a consultant phoned me and confirmed that it's been canceled but I see now the nightmare continues. Can my home internet be canceled once and for all and Vodacom stop sending me bills for it when I no longer even have the router they collected in January
