Poor service delivery from Openserve and Telkom

Openserve and Telkom have been installing fibre in my area since last year. The fibre is not activated yet and they have literally disappeared. Apparently there is a fault with a cable which some people from Telkom and Openserve came to inspect last week. A technician was supposed to have been sent to fix the issue but we are still waiting. I live in the Mayfair West/Langlaagte North area. How can they leave without completing the installation? I want someone from Telkom or Openserve to contact me to explain what is happening. This is very unprofessional behavior. Your service leaves much to be desired. Please give us an update on when we can expect the fibre service to be activated. Don't just disappear without an explanation or without even completing the job.
