Telkom Call Centre does not help its customers

I tried to get hold of someone at the Telkom call centre to cancel a fault. I held on for 82 minutes but no agent was available (ridiculous) to do this. The only reason why I held on so long was because if I did not cancel the call and a Telkom technician was dispatched in this case I would incurr a cost. I could find no other way to cancel the fault. I am hoping someone from Telkom would phone me back to cancel the fault.
