Cancelled my account 3 months ago, still billed

I have phoned about 3 months ago to cancel my telkom line and internet. It was done on the day via the call centre. I no longer use the phone line or the internet and do not have the internet service anymore.<br> <br> I am still being billed now every month for a service which i already cancelled.<br> <br> Can you please resolve this and just get this simple request right.<br> <br> Thanks.
