Telkom is the worst service provider ever!!!!!!!!!!!

I have been trying for a few months to cancel my internet service with Telkom. For months I sat on the line trying to get through to the cancellation's department - never ever getting through because of the long waiting time. Tried cancelling my service online, no joy here as well. Tried calling the technical department to issue me with a new username and password as the email address used when registering was no longer in use. The technical department smsed me a new username and password and that didn't work as well. No one at Telkom is able to assist me with either sorting out my username and password issue or cancelling my internet service. So in the meantime I am stuck paying for a service I dont want or use....Telkom is ripping us off!!!!!!!!!!!!!
