Poor Telkom ADSL Service

Mount Pleasant area in Port Elizabeth has according to a Telcom Technician over subscription of 135%. This means that although the lines test OK, there is data congestion that is so bad that a 4 meg line drops to below 1 meg and you cannot even stream Netflix of Youtube. Report it 20 x and all you get is promises. 1,5 years of callouts and still nothing. Can the Public Protector take on Telkom and force them to give the service a consumer pays for as the quality of service is disgusting.
