Cancelled fault TWICE and technician STILL arrives

I reported a fault on my intermittent line on Friday, however, the line became more stable over the weekend. On Monday, I waited 27minutes on the line and cancelled my fault call, the agent confirmed the fault call cancelled. On Tuesday I recieved an SMS confirming my Fault call was being attended to - i then called the call centre again, waited 25minutes on the line and was told that the call was cancelled. I then recieved a call THIS MORNING, and the technician was at my gate. How can you tell a customer that the call is cancelled TWICE and not relay this to your technicians. I cancelled my call becuase the line was working. Your service is shocking when it comes to your call centre. Also if you report a fault there is no communication prior a technician coming to your property - people work and do not sit at home all day waiting for Telkom to come sort out a faulty line. I am so appalled by the service i have just recieved that it doesnt put much faith in me retaining the product.
