No respnonse from Telkom on cancelation of contrac

I have been trying to get confirmation from Telkom on my outstanding balance and to close my ADSL account from December. I have emailed all relevant info with signed copies of cancelation request etc almost on a daily basis, I have tried calling their call centre and have been pushed from pillar to post, with no assistance what so ever. there is no communication from Telkom what so ever. <br> This is disgusting customer service.
