Cancellation of Residential ADSL line

It has been almost 2 weeks that I have been struggling to get hold of ANY Telkom Agent.<br> <br> I am trying to cancel my ADSL and Telkom services.<br> <br> When I contact the call center the call gets disconnected after holding for 50 minutes. Time and Time again.<br> <br> My e-mails also receive no response.<br> <br> Where are all the sales personnel that sold me these products / services? Can't they cancel the service?<br> <br> <br> <br> <br> <br>
