Telkom prematurely cancelled my adsl line

i requested my adsl line to be cancelled at the end of the month ( have proof ) with telkom Came home today 06 april only to find its been cancelled. I have been on 4 calls with a total of 3 hours holding close on 4. Are they that bad. i have paid every month without fail and now my line is cancelled. I have NEVER know a company with such bad service levels. Why do we put up with this. So disgusted with Telkom.
