Technician needed urgently

8 months ago a fault was logged, many follow up calls have been made. line is super unstable... requested a technician in September and still have not seen one at my house! Wake up Telkom! your incompetence is disgusting and your call centre is an excuse as the people working there dont know what they're doing! A technician is all im asking for! What are you doing about it? I am disgusted!
