Not sourting out the lack of ADSL problem

After 4 visits to site, a temporary line is left d***** in the garden.<br> 4 reports back to fault dept by Technicians to replace a cover on the box connection are ignored. This dates back to last year. This open connection box with wires exposed to the elements is apparantly the source of the problem, or so we have been told. The lid left lying on the ground below the pole. Wish I could supply a picture of this. We have constant total breakdowns on the ADSL line.<br> Requests to clip trees are ignored. In desperation we have done this job ourselves to facilitate the Technicians.<br> We have had interrupted ADSL for 3 weeks now and intermittent crackling line so bad we cannot use the new phone.<br> What do we have to do to get the service we are paying for ?<br> <br>
