Worst service ever!!

We cancelled our Internet and now we need to get hold of telkom to cancel the line otherwise we will be billed for something we never use. It's been a month trying to get hold of Telkom but everytime we phone we get put on hold. Today we were holding for an hour and still we are not able to get helped. I feel that Telkom is deliberately ignoring their customers to avoid further disappointment but little do they know none of their customers have anything good to say about them. It's a shame that Telkom is the only company that provides Internet services if it wasn't for that Telkom would have been non existing long ago.
