App**** for a line a month ago and no response yet

I app**** for a ADSL line on the 3rd of October 2015 and was told it would take 7-14 working days for someone to come and install. When I tried following up two weeks back, I was told that there is no order on the system. I have spoken to numerous people at different points who all keep telling me that the matter has been escalated only to be told in the end that there is no order on the system. I was given an order copy and the number was CM***. Please resolve this ASAP and advice when I will have someone coming over and installing the line. I cant be going back and forth forever and keep waiting for someone to come install when you people cannot even acknowledge the order. I don't have more time to waste and neither do I have the time to reorder this and wait forever for someone to come again. Please provide me with a course of action for this matter to be resolved. ASAP.
