ADSL cancellation

I cancelled my ADSL line effective 31/12/2017 before moving out of my apartment. I e-mailed the completed cancellation form as instructed to the e-mail address on the form. The agent I dealt with is Roxanne Luzaan Saalmans. I then moved overseas and assumed the matter was in capable hands. Upon my return to the country I find out that Telkom is still billing me and as of July 2018 they had written these amounts off as bad debt. This is blatant ***** and Telkom wasn't ever entitled to this revenue as my line was cancelled and my credit record is now affected. I have logged numerous disputes ( see dispute number ********** 6) and have been promised responses and follow ups and have received nothing.

I want this issue resolved and removed from my credit record as it is entirely **********!
