No Internet

Saturday 12 March 2016 my Internet stopped working completely. Sunday 12 I lodged a fault and had somebody come round a week later. The guy came in took a look said problem was on lines. He walked out diapered never saw him again he does not answer calls either. Logged another complaint another person came around and said he will sort it. He said fault was in lines. 2 days later I go into Telekom again and they tell me the fault was closed... how can u close a fault when nothing has been repaired I have had no Internet WiFi absolutely nothing now for 2 weeks. What do I do when Telekom guys can't fix this. I'm busy paying for Internet when I'm not using anything. This is shocking where do I go from here. Nobody from Telekom wants to help. I want this sorted ASAP
