Waiting too long for ADSL

I app**** for ADSL on 5 June. I was promised that it would be completed in 3 weeks. However I am still waiting. When I called yesterday, the lady at the call centre asked for my ID number and then she said nothing for 22 minutes! I tried again today and after holding the line for 31 minutes I was told that the system is not functioning properly. It is extremely frustrating.
