Lack of service and communication

My service was lost 12 days ago due to a technician breaking the wire to my unit. Have phoned continuously every day with a promise that I will receive feedback on my problem which only happened once. A technician came out eventually but said the technician who broke the wire would have to come back an do the job. That was 3 days ago despite daily phone calls all of which take an average of at least 15 minutes on the line to get any response
