Poor Technical Service

On 09.12.2015 we logged a call 275CRK091215 as our 10meg line just dropped its sync to 6meg and was disconnecting intermittently. Got a progress update on 23.12.2015 stating that a technician was attending to the fault. There was apparently a one of the main cables that was damaged and needed replacement. The call was closed off on 29.12.2015. when checking my router sync speed it is still on 6mb while we are paying for a 10meg line and bare in mind our line was syncing at 10meg before this problem started. On 30.12.2015 I had to log a new call 156CRK301215 to attend to the problem. This call was closed off on 31.12.2015 without a technician even arriving at our house or the problem being resolved. Contacted customer service again and I was told that I had to log a new call AGAIN as they can't do anything about calls that was closed. Frustrated with the poor service I logged a new call 54CRK311215 on 31.12.2015. Today again I receive the message that call had been closed. Called my wife at home to check the sync speed and tells me nothing had been done and no technician was at our house again. What type of service is this where a technician of Telkom can simply close a call?
