A month and a half for a adsl wall jack!

I placed an order for a ADSL wall jack to be added to the our existing ADSL line at home on the 9th of april. I was told it would take two week for the technicians to come out to install it... Two weeks later I phoned to asked why I had to wait for no one to show up. They told me that the techies were at my house but no one was there, even though I was at the house all day. They said sorry and rescheduled for the 15th of May, which I HAD to accept.<br> At 4 o'clock on the 15th I phoned again and asked what is happening, they told me that the call was closed because the job was done!!! Spending the whole of Monday(18th may) on the phone trying to find someone who can assist me I got through to \Javiso"and he promised me that he will find out what is going on and sort it out. I phoned again the next day and was told by three people that there is no \""Javiso\"" and that my request/call is still closed! Every single time they tell me to hold to get a manager they put me through to a different agent."""
