Honouring my cancellation request

I am so sick of Vodacom fibre, I have cancelling my services with you for over 3 months now and to date nothings has happened instead you keep billing me although I have emails confirming that there will be no further billing. Every time I call a new cancellation request is logged on top of the already existing one...why ???? Your entire team lacks customer service, professionalism and with some plain rude. You were the worst before and I thought you’ve improved but it turns out you are getting worse, totally disgusting level of service and a team that is ***********.
