Worst customer service

I have been calling Telkom to get one problem resolved over and over. Firstly the call centre agents don't understand their resolution times, they explain 72hrs differently. Secondly they have stinking attitudes. To top it all I was called by this guy who sounded very bored on the phone so early in the morning to tell me that my query has been resolved, only to find that nothing was resolved. I had to call again for the 4th time and I was told the guy didn't do anything, and I must wait for 24hrs. I can't deal with this drama and very unprofessional agents. Telkom must cancel my contract today, and I will not pay anything not even a cent. I'm sick and tired.
