When I got home at about 1pm, my hub had flashing green lights. Checked cables and rebooted hub, same result. Last time this happened the engineer replaced the hub. Tried text contact with support, but only got automated responses. So phoned customer support, 25 minutes later and Indian lady answered my call. After a few checks and switch off/on again she said she would book an engineer to visit, between 4pm and 7pm on Monday. This leaves me the whole weekend with no internet, but I shall still be charged £43.74 for the month plus I have a letter saying it is going up by £3.50 because of their wonderful service. By the time it is up and running again it will be the best part of 4 days. Should not be charging that much if they can't make prompt repairs. Totally unacceptable.
