for over a week now there has been no signal (inside or outdoors) in Penarth. There was reported maintenance at the start of last week for the area which killled the signal for 3 days but now its showing that the work has been done but there is no signal at all.

how do i go about reporting this? as its unacceptable that the system should be down for this long. I can at most get a 1 bar signal extremely briefly for a few seconds and then its gone thus turning my phone and wifi hub (from 3) into some rather expensive paper weights.
