useless service

Technician came out to reconnect my line on the 9/4/2016. Which was not totally completed. He said that all was working fine except that he needed to go and unblock my line as I could only receive calls which he was supposed to have done that afternoon. Now a week later and am still waiting for this to be done. Logged the fault on Monday and have followed up with no success. FRIDAY 15TH they tell me technician is busy with it. When I phoned through today again I get told that a technician has not been assigned as yet. Does anyone know what they are doing there???
