NO CANCELLATION

10/2015, I cancelled my line. Got billed 11/2015.Contacted Telkom, whereby I was told I never canceled. I then sent the cancellation mail again. 05/12/2015 I received a mail confirming cancellation. 02/2016 I got billed again. I called Telkom again to inquire, why I've received a bill of over R 800. 00. I was told, I never canceled. I forward all the mails to the consultant, whilst she was on the line. She assured me that the cancellation will take place. On asking what about the monies paid, she informed me that, once the cancellation took place. I can call in and dispute my bill and request a refund. WHY THE HELL MUST I GO THROUGH THAT, TELKOM STAFF NEGLECT THEIR DUTIES. TELKOM SHOULD SEE TO ALL OF THIS BEEN DONE AND MY MONEY REFUNDED TO ME!!!!! I have a Telkom Internet Service on my other Telkom line ***, that offers 100GB per month, this service is so slow and breaks up when there's a slight wind, because our lines got so many joins in, at the end of the month, only 9% of the package was used. Can't view videos, info required, etc. This costs me over R 1000. 00 per month. I was told I cant downgrade, as the service will be worse.TELKOM SERVICES ARE TERRIBLE!
