line still not canceled

i called in november last year to cancel my adsl and telkom line i was then sent a cacelation form to fill in and mail off wich i did i got a responce from cancellation saying they have received the form and this prosses will take 30 days

.i then gave them 30 days and called again caus nothing was done which they then came back wit a excuse saying my Sp blocked the line which was a bull story as i had a ref from then saying it was released which i then convade to telkom they then said fine line is canceled

i now still getting bills to pay telkom account which should have ended end december but till now nothing has been done

no please tell me how do i get telkom to get off there asses and cancel my line as i dont want to pay for there service that sux and dosnt work half the time

i dont even have a handset or adsl router in my house anymore iv gone the wireless rout threw a diffent isp since end december last year hence why i wanted all my telkom services canceled i have spoken to diffent people multiple times on this and still no luck i even have copies of emails to and from telkom

i have even tried the telkom groupe on facebook but they just as useless
