Appalling. They cut us off without warning. We phoned, they said another company had taken the line (VB are required to give you notice if this has happened, so it might not have been true. Five months into a 24 month contract so we couldn't afford to leave even if we'd wanted to). Took five (working) days and ten hours of a combination of phone calls, and chat on their execrable app to restore own broadband connection. Their helpline drops calls, a lot, one of the 'help'ers phoned us back when this happens, two did not.
