Telkom is useless

For 2 days I have been trying to cancel my ADSL with Telkom as it is slow and keeps dropping.<br> I have emailed, been on the phone for over 3 hrs and still no response. Going into a branch means you need to stand in a queue for another hour. Why can't the help lines assist, why must we listen to a recorded message with them offering packages when they ca't even handle the ones they have????
