Telkom Landline not Cancelled

Last year 2016, i app**** for a business landline with Telkom, the line was operation and i didnt have problems. The business did not do well this year and so i app**** for cancellation of the landline in June, tell you what we are in December and i still have not been properly helped. I went to different Telkom shops in the Cape, was told to wait its still in process, called numerous times and still nothing has happened. Eventually someone helped me in November and told me to resend the form of which i did, the problem i have is that every month i get billed but and its just pilling up but my cancelletion has not been processed.
