Cityfibre ... arghhhh
The company installing fibre ... and cutting other's phone lines without care as they put ducts/cables in without any care about current infrastructure.
I know someone who, along with several people on her road, has now had their line broken 3 separate times by careful Cityfibre "installers". TalkTalk are crap but when they get complained at they complain to Openreach and the poor engineer was pulling his hair out (again) as he was tracing multiple cable breaks in multiple locations ...
